Granting winter hikers adequate surface traction on the trail is the Coldspark UltraDry’s Monolith outsole. It is based on the dual-density ColdHold compound, giving it the capability to produce enough grip on slick and snowy surfaces.
The multi-directional lugs engineered along its perimeter allow the foot to hold its ground over uneven terrain.
Coldspark UltraDry’s stable midsole
This Vasque boot gets to provide ample ground stability and cushioning with its molded EVA (ethylene-vinyl acetate) midsole. At its midsection is an embedded shank made of thermoplastic polyurethane that provides added underfoot support and stability.
Helping the midsole deliver even more comfort is the boot’s removable footbed. It has a cupped design that offers extra support and perforations that boosts breathability.
Coldspark UltraDry from Vasque features
The Coldspark UltraDry’s breathable upper is a combination of waterproof PU-coated leather (with a thickness of 1.8 mm) and softshell textile.
It comes imbued with two essential technologies: Vasque UltraDry and Thinsulate by 3M. The former promotes breathability while keeping the entire gear waterproof, while the latter—as its name suggests—equips the boot with 200 g of thermal insulation.
Over at its heel is a molded TPU yolk that delivers additional rearfoot support. Its collar is lined with fleece, granting added comfort.
Completing this winter hiker’s upper is its quick closure system. It is made up of flat laces and three different kinds of eyelets—D-rings, opens hooks, and lace tunnels. The pair of D-rings at the end of the eyestay allows wearers to lock their snow gaiters in sort.
