Not sure which insole? 30-second finder

A five-layer insole for running shoes, gym sneakers and soccer or court shoes. Its core is a full-length 3 mm layer of high-density, high-rebound EVA, with deep-absorption pads set into it at the heel and forefoot. Underneath, a 2 mm anatomic TPU shell runs from heel to midfoot with a molded arch and metatarsal support, on a carbon-fiber-look PU base.

These are not the generic foams of cheap insoles: every layer is a high-quality rebound or absorption material, chosen for sport. A breathable microfiber top moves moisture away during long sessions. About 4.5 to 5 mm thick. EU sizes 36 to 45 (US 5 to 12), sold in pairs.

Good to know

How to fit them
  1. Choose your usual EU shoe size.
  2. Take the factory insole out of your shoe.
  3. Place the Step Balance insole with the heel right at the back and press it flat.
  4. Start with shorter periods: feet usually need a few days to get used to arch support.

Half size, such as 42.5? Choose the size below (42). Our insoles come in whole sizes, and the smaller one fits inside the shoe without pressing into the toe box.

Please note

Step Balance insoles are comfort and sports accessories, not medical devices. If you have a diagnosed foot condition, ask a podiatrist or physical therapist which type of insole suits you.
