It features advanced technology including a GORE-TEX lining and an Air-Active footbed which means the boot is waterproof and breathable. A notable feature of the Respond Mid II GTX is the aggressive Meindl sole unit which has a deep profile for excellent grip and stability. The sole unit is made from 22% recycled rubber which makes the Respond Mid II a sustainable option. We use rubber offcuts from our production and therefore we can reduce raw material usage and transport. The rubber has been designed to maintain the well known Meindl quality level of abrasion and grip. This boot is ideal for tracks, trails and adventurous travels.
