Palmilhas PowerStep Maxx | Palmilhas ortopédicas corretivas para pronação excessiva, máxima estabilidade

The listing says full length, no trimming required. Powerstep says most styles follow full US shoe sizes. If the toe area is slightly long, you can trim along the printed outline, using your shoe's factory insole as a template. Walk in anytime and we'll fit you in person.

The listing says it fits shoes with removable factory insoles. Powerstep says to take out the shoe's factory insole first so your foot doesn't sit too high. It also says full-volume insoles can be too thick for low or narrow shoes, and suggests thinner options in that case. Bring your shoes in and we'll check the fit.

Powerstep suggests wearing them up to 1 hour on the first day, then adding about an hour each day. If you feel comfortable after five hours by day five, you can wear them full time. Some people need up to two weeks. If you're sensitive, try 30 minutes at a time.

The listing says spot clean with mild detergent and air dry. Powerstep says not to immerse insoles in water. Spot clean with mild detergent and a damp cloth, air dry only, and let them dry completely before putting them back in your shoes.

The listing describes an odor-control polyester top cover, a foam top layer over an EVA base, and a polypropylene shell with a 2° medial post.

The listing describes a firmer shell and an angled 2-degree heel post that help stop your feet rolling inward (overpronation), a firm but flexible neutral arch, a deep heel cradle, and dual-layer cushioning heel to toe.

The listing says 6+ months depending on use. Powerstep says to replace insoles as soon as you notice less comfort or support.
