Bottom line

Lightweight, warm, and crampon-supportive—these remarkable traits describe the Asolo 6B+ GV boot quite accurately. Indeed, such qualities, on top of a few others, put this gear among the brand’s top-of-the-line creations. That said, those who wish to take advantage of everything this boot has to offer must first get past its moderately lengthy break-in period. To sum up, the 6B+ GV’s excellence on almost all fronts gives it an edge against competitors. It just needs time to loosen up completely.

Good to know

  • Asolo’s 6B+ GV is engineered with a combination of technical features that give mountaineers the capability to ascend elevations in biting conditions. Its waterproof and insulated upper is tucked under a tough lasting board called Duo Asoflex Ascent which is made primarily of nylon and fiberglass.
  • The boot’s sole unit is made up of two primary components: the Vibram Vertical outsole and a rigid midsole with crampon attach points. It comes complete with PU anti-shock inserts.

The 6B+ GV from Asolo is a generally true-to-size, high-cut mountaineering boot for men and women. It is offered in whole and half sizes in standard width. The women’s version is built on a gender-specific last. The footwear’s fit may be personalized with the use of its quick lacing system.

First in line to receive the assault of the mountainous terrain is the 6B+ GV’s rubber outsole, called Vibram Vertical. This component—a resulting product of Asolo’s partnership with Vibram—promises traction on extremely rugged surfaces, all thanks to its sticky construction and aggressively designed lugs. It has a hook-like feature (a.k.a heel brake) that grants mountaineers additional descent security.

This boot uses a stiff yet cushy midsole for underfoot comfort and ground stability. It is equipped with PU inserts, one at the heel and another at the forefoot, for extra shock absorption. For added cushioning and support, on the other hand, this stabilizing layer is paired with the Lite 3 anatomic footbed.

The Asolo 6B+ GV’s over-the-ankle upper is a combination of microfiber and water-resistant Schoeller textile. Its liner is crafted with Gore-Tex’s Insulated Comfort technology, granting wearers protection from the elements with adequate warmth and breathability. The lower region of the boot is covered with an abrasion-resistant rubber rand which is integrated with the sturdy and supportive Heel Locking element.

Most of the boot’s eyelets are riveted hook and loops made of metal, except for the fabric ones located at the ankle zone. The laces making their way through these combination eyelets are synthetic.

  • This mountaineering gear can be equipped with automatic (step-in) crampons.
