How we test products

Grip socks behave very differently on a Reformer carriage than they do on a hardwood floor at home, and differently again on a hot Pilates studio's vinyl mat. A sock that looks fine in a product photo can slip in week three on a sweaty footbar. The only way to know is to wear it in the room it's designed for.

Each pair tested goes through the following protocol:

• A minimum of 15 sessions across at least three different studios.
• A mix of classes: Reformer, mat Pilates, Barre, and at least one hot session.
• At least three of the sessions are with a working instructor who has not been told which sock is being tested.
• After every five sessions: a photographed sole-condition check and a written note on slip incidents, fabric integrity, and cuff retention.
• Wash cycle test: 30 cold-water wash and air-dry cycles with photographed before/after on the silicone pattern.

• Silicone coverage area, pattern density, and curing quality.
• Combed-cotton percentage, staple length where the manufacturer publishes it, and post-wash fabric integrity.
• Arch-support band tension, before and after 30 washes.
• Cuff retention — does the cuff stay above the ankle through a 50-minute Reformer class?
• Slip events per session and the surface on which they occurred.
• Comfort scoring on a 1–5 scale from each tester, at session 1, session 5, and session 15.

Our founder, Faith Walsh, runs the initial wear-test on every product before it ships. Independent instructors who are paid for their time — not the product — run the parallel tests. We do not ask testers for positive reviews and we do not offer the product for free in exchange for a write-up.

When a review compares our socks against another brand's, we buy the competitor's product at full retail price and put it through the same protocol. We do not accept free samples from competitor brands.

We publish the full method, the raw scoring, and the conclusion. Where a product performs poorly on a single dimension but is otherwise strong, we say so rather than averaging the score into a single number.

We do not publish promotional language from manufacturer press kits as if it were our own finding.

Every product on this site is re-tested at least once per year. When a brand releases a new version of a sock we have reviewed, we re-test it from scratch before updating the review.
