Insoles from the 3Feet range are selected according to your arch type - 3Feet Slim Mid are designed for a medium arch.

The 3Feet Slim model is exceptional because the material under the forefoot is only 2 mm thick and is suitable for footwear where there is insufficient internal volume, or for those with high-volume feet who still appreciate longitudinal arch support. Longitudinal arch support enables better axial foot positioning, better pressure distribution over a larger foot surface area, better force transfer (cycling, skating and so on) and greater comfort. The shaped heel cup seats the foot better in the shoe.

3Feet Slim Mid insoles are also suitable for cycling shoes, which are often very tight and may not have room for other models in the 3Feet range, especially if the cyclist has a high instep and wide feet. They work equally well in tight-fitting skates, in precisely fitting formal shoes and so on.

The front part of the insoles can be trimmed off (along the marked line) to create "half" insoles for shoes. This is useful if it is not possible to remove the original insole.
