Exclusive foil made from recycled materials, located directly under the foot to reduce the impact caused by hard surfaces and recover the energy inverted at each stroke. Literally, it is a layer of material that bounces between the asphalt and your feet!
This sole is dedicated solely and specifically to the trail, it is composed of blocks that are directly placed below the metatarsus and "claws" on the front of the shoe for the relief and descents.
A toe whose design allows the fingers to relax and expand naturally, keeping the thumb straight to enjoy more stability and a more powerful takeoff, which will give you better performance when running.
This innovative hook facilitates the position of "ghettos" to not have to fix them on the sole. All this to avoid the accumulation of stones inside the slippers.
