The New Updated La Sportiva Helios 2.0 gives you the same great Trail Running features you know and love about the original Helios, now with an upgraded lacing system, new felt overlays to areas of high abrasion, a modified heel cup, and coming in with a slight weight reduction. This gives them an even better "glovelike" fit, and even more lightweight to give you the ultimate fast trail running shoe. It has been designed for training and running on hard, off road tracks, and is best on rocky uneven terrain. It provides a super sensitive and minimal natural style of running, and is ideal for everyday wear and for running on trail paths on rocky terrain thanks to the Cushion Platform™ insert that provides greater shock absorption. The new quick lace system includes a cinch buckle and keeper loop to help speed up lacing. The EVA and Mesh uppers are extremely lightweight .The slip on construction method allows to pull on the boot easily and ergonomically. The MD EXTRA Light sole with FriXion blend and AT lugs guarantees a perfect grip on slippery terrain.
