Altra Lone Peak 6 Women's Trail Running Shoes Moderate stacked trail shoe with an aggressive outsole and integrated stone guard for anyone looking for a durable and protective trail shoe that can conquer any terrain. Quick-Dry Air Mesh Upper An update on previous versions, the quick-dry air mesh used on the upper part of the shoe is not only more breathable, but it has improved durability and security. The soft and flexible mesh of the upper allows you to run through wet and rainy conditions as the upper does not retain water, keeping you light on your feet. The upper also features updated drain ports that improve the flow of water ideal for trail running. The foot shape toe box allows your toes to spread out more naturally, offering greater comfort and stability in uphill climbs and downhill descents. The upper has been trimmed down slightly, which has helped make the 6 lighter and more flexible than its predecessor. An updated stone guard is much lighter in weight while offering the same level of protection. This has been done by effectively creating a pressure map of the foot on the stone guard and creating open perforations in the spots where there is very little pressure. This allows for less material to be used while offering protection in the necessary areas. The lacing system has been updated with additional lacing that provides a more secure fit across the forefoot, reducing in-shoe slipping. Finally, the heel loop makes transporting muddy shoes indoors is quick and easy. Altra EGO Midsole The Lone Peak 6 features an EGO midsole that adds cushioning and flexibility ideal for trail running. Maintaining the same stack height of 25mm as its predecessors, Altra have been able to increase the cushioning and durability of the midsole when it comes to the latest versions of the Lone Peak
