Rugged Trail Runners having tactical features starting with Altama's legendary Panama Sole technology. Using sticky SOFROC(TM) rubber that wraps up in the arch to aid in fast roping, we've turned a typical trail runner into a tactical machine! Specifications: Our midsole cushioning is compiled of multiple layers to protect the tactical warrior. We start with a dual density EVA midsole; slightly softer in the heel for added cushion and rebound. We embed a full length Rock 'n Roll Plate(TM) on the bottom side to prevent bruising from rocks and roots. The strobel insole board is lined with an additional layer of EVA for that extra cushioning. The upper has many features not found in most trail runners today. The molded rubber toe assists and protects the foot when having to kick in a door. The injection molded TPU heel clip adds support and provides superior stability. We've constructed the upper for maximum breathability. Using the best microfiber PU as well as breathable nylon mesh, we laminate the materials in such a way to promote superior air flow, thus a healthier foot environment. The nylon loop lacing system helps for quick adjustment. On the heel you will find a nylon pull loop to assist when pulling on your shoe. Our insole is an Alta-lite(TM) dual density blown PU insole for exceptional cushioning and support.
