La Sportiva?s latest innovation in mountain running shoes has been in development for over 2 years and adresses the need for lighter products that are low-to-the-ground and well cushioned. The new MorphoDynamic technology addresses these needs with a midsole that adapts to the trail while providing a well cushioned ride to protect the foot from impact forces. By using a soft, lightweight PU foam that fills the MDI (Morpho Dynamic Interface), we have created an increased amount of cushioning material that also drastically reduces weight. These cushioning MDI adapt to the running surface creating a smoother ride and increasing the surface area contact of the outsole with the running surface. They absorb the features of the trail while at the same time absorbing the impact upon foot strike. On top of the PU layer is a firmer EVA layer which provides stability for the foot in the form of an ergonomically shaped midsole that works in harmony with the new revolutionary slip lasted upper which hugs the foot and provides a more responsive ride. The result is a low profile, stable extremely responsive and cushioned ride with no sacrifices.
