Solid Gear and OrthoLite® HybridTM comes with an unprecedented share of eco-content in an insole. The pending patent formulation uniquely blends recycled rubber and production waste foam, which gives a total of 40% eco-content for uncompromised performance with less impact on the planet. This insole comes as standard in selected Solid Gear styles with wide lasts, however after continues use for six months, we recommend that you switch the original insole to a new fresh one certfied with Solid Gear. Extra padding in heel. Also suitable for shoes with ESD function.
