How it fits

Powerstep insoles are sized by your US shoe size. Each size covers a range (for example, size C fits men’s 6–6½ and women’s 8–8½). Full-length, 3/4-length and SlenderFit insoles use different charts — match the chart to the insole.

If you need to trim, Powerstep recommends using your shoe’s factory insole as a template.

Break them in gradually: Powerstep recommends wearing new orthotics for up to one hour on the first day (30 minutes at a time if your feet are sensitive).
