Every detail has been thought to keep weight at a minimum without compromising the structural and protective features fundamental for racing. The structure of the uppers is created using a lightweight, high frequency frame with a soft, breathable and comfortable EVA net. Maximum care and attention has been given to flexibility, to promote natural foot movement without constricting the front flex zones. Helios SR uses a snug fitting Slip-on construction upper for ease of use. The injected midsole with Morpho Dynamic technology works in synergy with the FriXion XT dual density sole, to provide optimal shock absorption. Features such as the reflective inserts, the reinforcement zones on the toe and heel in micro fibre and the internal protective silk screening, have been created to satisfy the most demanding off-road runners. Helios SR takes minimalism to the racetracks.
Size is much smaller than other La Sportiva shoes size 47.5.

The La Sportiva FriXion® compound is the result of extensive R&D aimed at creating outsoles with parameters of grip and durability that respond to all types of use and terrain.
The Frixion range uses 5 custom formulated compounds from mountain running to climbing shoes.
EVA - INJECTED Highe degree of cushoning and high elasticity of the fabric. These features assist “push off” during the propulsion phase while running, making these models who use injected midsoles, ideal for use on off-road trails. Furthermore, EVA Injected midsole drastically reduce the “squash” effect of the EVA over time, allowing the product to mantain the same features for its entire duration.
The La Sportiva Mountain Running® footwear adopts 3 different kind of midsoles depending on the style and on the needed performances
ROCK GROUNDS: High performance soles indicated for use on hard and rocky ground. They maintain optimum performance levels even on wet ground thanks to the ‘VA’ lugs used at crucial points on the sole which keep slipping in check on bends. With Morpho Dynamic Technology.
