Four Koprez prices for one sleeve, one price for One Compress
KnitPair appears in the size chart table below. We publish no fibre split and no compression figure.
Koprez's main product page, koprez.com/products/foot-sleeve, read 13 September 2026, shows $39.99 for one sleeve, struck through from $79.99, with a badge reading "50% OFF". Underneath it sits a quantity tier table: "1 Sleeve $39.99 Each", "2 Sleeves +Free Shipping $10 OFF $34.99 Each", "4 Sleeves Most Popular $40 OFF $29.99 Each", "6 Sleeves Best Value $90 OFF $24.99 Each". Two sleeves bought there costs $69.98.
A second Koprez page, koprez.com/products/foot-sleeve-pair, read the same day, is priced at $79.99 for two, struck from $159.99, and its own tier table then prices "1 Pair $10 OFF $69.99 Each", contradicting the headline above it. The homepage tile shows $79.99 with no badge at all, which is the product page's struck-through price presented as the live one.
Then there is offers.koprez.com/foot-sleeve-deg-bogo, read 13 September 2026: "Koprez® Foot Sleeves $39.98 ($159.98 value) Buy 1, get 1 free, 2 sleeves at $19.99 each. Regular price $79.99 per sleeve." That is the cheapest published Koprez price for two sleeves anywhere on their properties.
The regular prices Koprez publishes for a single sleeve across its own properties on one day are $39.99, $79.99, $69.99 and $19.99. The highest is four times the lowest.
One Compress has the opposite problem. Read from onecompress.com on 13 September 2026, the price is $49.00, compare-at $75.00, badge "SAVE 34%", identical across all fifteen variants. The same $49.00 appears on onecompressbamboo.com, the brand's second live storefront, where the product page showed "Sold out" on 13 September 2026. There is no multi-pack on either store, so a buyer who wants two places the $49.00 order twice, which is $98.00.
The headline gap is $39.99 against $49.00, and the two-sleeve gap is $39.98 against $98.00, which is the one that matters, because the usual reason for a second sleeve is that a person has two feet.
The count problem, which One Compress has worse
Koprez's single product page is titled "Koprez® Foot Sleeve", singular, and the description gives no count. The only place a number appears is the quantity tier selector, whose first option reads "1 Sleeve", which is thin but is still an answer before checkout, read from koprez.com on 13 September 2026.
One Compress does not have one. The product is called "Premium Anti-Fatigue Bamboo Footsleeves", plural, and read 13 September 2026, no count appears in the title, price area, variant options, description or size guide, across all 15 variants at $49.00. There is no pack, pair or quantity option naming a number anywhere on the page. The only brand-written use of the word "pair" sits inside a returns FAQ: "Send them back and we will get another pair sent out."
A buyer comparing $39.99 to $49.00 is comparing a price to a price, and a buyer comparing $39.98 for two to $49.00 for an unstated quantity is comparing a price to a question.
Returns: 30 days against 60 days the policy does not back
Koprez's policy page, koprez.com/pages/returns-and-exchange, read 13 September 2026, says verbatim: "All products come with a 30-day trial, starting from the day the parcel is received." Returns must be shipped within 14 days of instructions, there is no restocking fee, refunds are stated at 5 to 10 business days, and a $9.99 "Perfect Fit Guarantee™" add-on at checkout buys a size exchange. Thirty days is not generous, but the advertising says the same thing the policy does: Meta ad id 1034503363082045, started 30 March 2026 and still active on 13 September 2026, carries "30-Day Money-Back Guarantee" in its own title.
One Compress publishes two different windows. The product page, read 13 September 2026, promises a "60-Day No-Risk Guarantee" and says: "Try them for 60 days. If you don't feel less foot pain and improved mobility, send them back for a complete refund." The refund policy at onecompressbamboo.com/policies/refund-policy, read the same day, accepts returns within "30 days of receiving your order" and requires items "returned in their original, unused and resalable condition".
The second half of that policy sentence is worth reading twice, because "unused and resalable" is hard to reconcile with "try them for 60 days". The promise a buyer sees at the moment of purchase is twice the length of the one in the document that governs the refund. If the returns window is what decides this for you, Koprez takes the row at 30 days that mean 30 days.
Ratings, and the customer counts both brands print instead
Koprez has a Trustpilot profile at trustpilot.com/review/koprez.com. Read 13 September 2026, it shows 4.3 from 765 reviews, with 82% at five stars and 9% at one star, and it carries the labels "Claimed profile • September 2022" and "Paid Trustpilot subscription".
On its own site the same day, Koprez publishes "4.7/5 Based on reviews from 500K+ customers" and "(10,242 Reviews)". Same brand, same day: 4.7 from a 10,242 review count on the page it controls, 4.3 from 765 on the claimed, paid profile it also controls. No third-party review profile for One Compress was read on 13 September 2026.
What One Compress does publish about itself, all read 13 September 2026, is five different customer counts: "800,000+ Satisfied Customers" on both homepages, "750,000+ customers put their trust in Onecompress" on the product page, "Join the 500,000+ Happy Customers" on the same homepage that carries the 800,000, "Over 170,000 people have chosen Onecompress" on an advertorial, and "Join 700,000+ happy sleepers" in Meta ad 2288785501955454. Koprez has the same habit at a smaller spread: 500,000+ on koprez.com, 100,000 on offers.koprez.com/Plantar-Fasciitis-Sleeves-EM, and "200,000+ people already wear them daily" in Meta ad 1650980879516949.
Ad footprint: 546 on one identity against about 842 across four
Read from the public Meta ad library on 13 September 2026, Koprez runs 546 active US ads on a single page identity, page 104789644587334, plus roughly 300 Google ads as advertiser "Mandala Group LLC". One Compress runs about 842 active US Meta ads as advertiser "Ksquare, LLC" spread across four page identities, "One Compress" with 364, "Pure Living Digest" with 290, "Clinic Discussions: Injuries, Relief & More" with 95 and "Reddit Relief: Stories, Discussions & More" with 93, plus roughly 300 Google ads of its own. Both brands had creatives that started on 12 September 2026, so both are spending now rather than decaying.
The structural difference is in the names. Koprez buys its 546 under its own brand. One Compress buys 364 under its brand and then 290, 95 and 93 under three page names that read like publications rather than a footwear brand. What is checkable about those three is that they are Meta advertiser identities operated by Ksquare, LLC and that the ads land on onecompress.com, and we are not going to assert anything about the bylines printed on them.
Koprez's volume has a tell of its own. Of 90 sampled active Koprez US ads read 13 September 2026, 80 carry a buy one get one free offer, about 89 percent. A discount that nearly every live creative carries is the price.
Ad id 1034503363082045 is the second tell. A Black Friday title that has run continuously since 30 March 2026 was five and a half months old on the day we read it, which is the context for every countdown, badge and struck-through price on either brand's pages.
What each brand claims, quoted and dated
Koprez claims outcomes with a calendar attached. Meta ad id 1412433000108659, started 10 March 2026 and still active, includes "Complete healing in 30 days or less" and "Biolateral Circular Compression that drives blood flow deep into damaged tissue for real healing", with a link description reading "Relief in minutes, healing in weeks." On koprez.com, read 13 September 2026: "Day 30 | Pain-Free, Wake Up. Step Down. No Pain." and "Relief starts instantly". On offers.koprez.com/Plantar-Fasciitis-Sleeves-EM the page says the product will "eliminate every symptom of plantar fasciitis forever in 4 weeks". Meta ad 1945703776383035, started 20 November 2025 and still active, is titled "Unveiling 2025's Breakthrough Cure for Plantar Fasciitis".
The mechanism names on the product page itself are milder and just as unquantified: "Biolateral Compression Zones, Six targeted compression zones work in harmony to maximize comfort and deliver support precisely where it's needed most", alongside "Instant Relief Technology" and "Premium Compression Fabric, More flexible than standard materials", read 13 September 2026. None of them arrives with a material, a tension figure or an mmHg value. The strap name that sounds most technical, "Polyaxial Support Straps that work like cables, lifting your fascia", is in ad 1412433000108659 and not on koprez.com at all.
Their authority claims differ by page, both read 13 September 2026. koprez.com says "we partnered with Anabelen "Annie" Aranton, a licensed physical therapist with decades of experience", while "Designed & endorsed by expert podiatrists" appears on one offer page only, offers.koprez.com/Plantar-Fasciitis-Sleeves-EM. Koprez also publishes "$218,000 in research behind it.", read 13 September 2026.
One Compress publishes percentages instead of timelines. The product page carries "87% noticed meaningful pain relief within 2 weeks" and "94% say it feels more comfortable than other compression", and the homepage carries "92% Feel Less Pain", all read 13 September 2026. No source, sample size, method or date is attached to any of the three.
The specifications neither brand publishes
Across the eleven koprez.com and offers.koprez.com pages read on 13 September 2026, the string "mmHg" does not appear, and it does not appear on onecompress.com the same day either, so the one number that defines a compression garment is unavailable for both. Neither publishes a fibre split. Koprez's material text reads "Premium nylon-spandex. Hypoallergenic, breathable, chemical-free." One Compress's reads "New Bamboo Material makes these the most comfortable eco-friendly socks on the market." Outside this pair, OS1st publishes its percentages, "24% LYCRA® Spandex, 76% Micro-Nylon", and sells a single FS6 sleeve at $24.99 on os1st.com, cheaper than either brand here.
On size count Koprez wins: six, S, M, L, XL, 2XL and 3XL, against five on One Compress, SML, MED, LRG, XLG and 2XL, both read 13 September 2026. On size charts they tie at the bottom. koprez.com/pages/fs-size-guide contains a heading and one image, Plantar-Fasciitis-Size-Guide-Mob2_1_1024x1024.webp, with an empty alt attribute and zero table elements on the page. One Compress's chart is also a flat image, 001_1f1abf2e-d070-43aa-bac3-2ad12f060aff.jpg. Neither can be copied, searched or read aloud. Free shipping thresholds differ as well: Koprez over $60, from koprez.com/policies/shipping-policy, against $75 on onecompressbamboo.com and $95 on onecompress.com.

Two columns, because the question is which of two brands to pay, and a third and fourth price would not change either answer. There is one row where the other two brands are the point, because it is the only line in the set where a reader can check a number against a tape measure without opening an image, and if you want the full rows with our own sleeve priced into them, the three-way version is at /p/koprez-vs-one-compress-vs-knitpair.

Who should buy Koprez
If you are choosing between these two today and price decides it, buy Koprez, and buy it from offers.koprez.com/foot-sleeve-deg-bogo rather than the main store, because $39.98 for two sleeves is $30.00 less than the $69.98 the same brand charges on koprez.com and $58.02 less than the $98.00 it takes to assemble two from One Compress. Buy Koprez if you need a 3XL, a label One Compress does not list; its largest is 2XL (koprez.com and onecompress.com, 13 September 2026). Buy Koprez if the returns window is what you are weighing, because 30 days in the marketing and 30 days in the policy is a shorter promise than 60 days the policy does not back.
Go in knowing three things, all read 13 September 2026. The struck-through prices are not a moment in time, given a Black Friday ad live since 30 March 2026. The Trustpilot profile reads 4.3 from 765 while the site reads 4.7 from a 10,242 review count. The healing and cure language sits in their ads and on their offer pages, and it is their claim rather than a finding.
Who should buy One Compress
There is one honest reason to choose One Compress over Koprez on the record above, and it is the material: One Compress is the only one of the two that names bamboo, and Koprez does not name it on the pages read on 13 September 2026. Everything else runs the other way. It is $9.01 more for one purchase, $58.02 more for two, one size fewer, no count of what is in the box, and a guarantee that is 60 days in the marketing and 30 days in the policy.
If you buy it anyway, treat 30 days as the real window, because that is what onecompressbamboo.com/policies/refund-policy says, and decide inside those 30 rather than the 60 you were promised. Check which storefront you are on before you order, since onecompressbamboo.com showed "Sold out" on 13 September 2026 and the free shipping thresholds differ, $75 on that domain and $95 on onecompress.com.
Who should buy neither of them yet
If you are choosing on compression, stop here. Neither brand publishes an mmHg figure, and no amount of reading their pages will produce one. The same goes for fibre content: neither publishes percentages, while OS1st publishes 76% Micro-Nylon and 24% LYCRA Spandex on os1st.com, read 13 September 2026.
If you are between sizes, wait. Both publish their charts as an image file, so there is nothing on either page you can hold a tape measure against.
