Helios III is the "door to trail" running shoe designed to train and compete on tough off-road terrain. It is a leisure vocation product with lightweight, breathable upper made with a unique iron-on combination of rip-stop fabric, single-sided mesh and reinforced TPU sandwich mesh. The fit is extremely comfortable and snug derived from the Helios SR model. The presence of the heel counter prevents crushing during the adjustment phase, while the soft, tight cuff with 3D foam pads ensures perfect comfort. The tread uses the highly durable FriXion Blu compound - perfect for use on hard and rocky terrain. The thermoformed toe cap contributes to the overall lightness of the product and helps protect it from bumps and abrasion. Our products deliver all-day comfort. La Sportiva NZ.
