Durable upper

Enhanced 360° breathability

La Sportiva Nucleo High GTX is equipped with Gore-Tex Surround. This technology gives waterproofing and breathability. It is mainly featured in outdoor footwear that suits warmer conditions. Warmth and moisture can vent out through the “spacer” and to the sides of the boot, keeping the foot comfy and dry in humid temperatures.
