How to Trim to Fit
- Take the original insole out of your shoe.
- Place it on top of the new insole, lining up the heels.
- Cut along the nearest trim guide at the toe (or trace your old insole).
- Slide the new insole in, heel first, and lace up.
These insoles are a comfort accessory, not a medical or orthotic device. If you have foot pain or an injury, talk to a doctor or podiatrist.
Pair them with our anti-slip grip socks, men’s non-slip grip crew socks and no-tie elastic shoelaces. Still choosing shoes? Read our best shoes guide and the race day checklist.
