A ‘macro membrane’ pattern serves as a visual cue (and a functional feature) on the Nucleo High GTX boot, which La Sportiva claims is its most breathable boot to date.
Hiking boots can get clammy, especially on warm days. But the quest for breathability in waterproof boots has taken a step forward in recent years. The waterproof/breathable membrane Gore-Tex Surround increases breathability in footwear.
This year, La Sportiva upped the ante with its Nucleo hiking boot by combining Gore-Tex Surround and a proprietary feature, Nano Cells (see the web pattern on the image above).
GearJunkie got a pair to inspect for this breakdown. The Nucleo is for sale now at REI, in men’s and women’s models for $199.
‘Nano Cells’ Make The Boot Unique
La Sportiva injects a polyurethane “web” onto the mesh upper to form what it calls Nano Cells. You can see a fine (breathable) mesh material through the PU web. This system protects the mesh yet allows air to circulate around the bottom of the foot, letting feet breathe.
Upper: Leather & Mesh
Nubuck leather is a rugged performer with a velvet-like surface. It is resistant to wear and a good choice for hiking boots. La Sportiva balances the leather with breathable, protected mesh (see “Nano Cells” section above) to give you the best of both rugged protection and breathable comfort.
