Ultra-performing and lightweight mountaineering boots with an ergonomic fit

The Garmont G-Radikal GTX boot fuses cutting-edge materials with innovative ergonomic and construction solutions. Semi-crampon-compatible, ultra-performing and lightweight, this boot is the ideal choice for mountain guides and fast climbers.

The erGo-last, combined with the Double Damper technology, offers a truly ergonomic fit. The upper in Lenzi Putek fabric offers top-level performances in terms of abrasion resistance, ruggedness, lightness and flexibility. The revolutionary G-Wrap technology is a fastening system which acts between the upper and lining in the area of the forefoot, wrapping the foot like a second skin for a fit never experienced previously. The double lacing system on the upper instead allows a differentiation in the tightness of the laces between forefoot and cuff, so as to be able to loosen or tighten the G-Wrap according to the activity, without modifying the tightness of the cuff.

The innovative Foot-Sleeve padding in stretch 3D mesh has been brought into contact with the foot itself rather than between upper and lining as in a classic construction. This padding, which can be removed and washed for greater hygiene, wraps the foot all around and creates an air space between lining and foot, for better aeration and less sweat inside the boot. The removal of the padding from the upper part means a quick dry effect: less water absorption and reduction of bacteria’s formation.

The G-Radikal features 'Alpine Tech Fit': a very precise and tight fit, with a tapered toe, which causes a reduction in the width of the sole of the foot.
This feature can make you perceive it as too narrow, especially if you are not a habitual user.
In these cases, or if you have not already tried this type of footwear, we suggest that you buy a size higher than the one you normally wear (for example, if you normally wear a 9, choose the size 9.5).
When first trying these boots on, be sure to loosen the laces all the way to the toe before putting them on.

GARMONT a.d.d.®
Garmont's Anatomically Directed Design (a.d.d.®) enables your foot's natural ability to stabilize, absorb shock, and propel forward. Fit is enhanced by closely matching design and function to the natural asymmetric shape of your feet:
The ankle cuff is lower on the outside and taller on the inside for better edging, greater overall stability and comfort when traversing and scrambling.
The tongue matches the asymmetric shape of the top of your foot and ankle. It is thicker to the outside and progressively thinner toward the inside. This anatomic shape keeps the tongue in place resulting in better control, stability and comfort.
Securely locks the heel in place for a precise fit around the ankle bones for better stability and support.
The shoe flexes like your foot for out-of-the-box walking comfort.
Features a straighter shape to accommodate the natural position of the big toe. With this design your toes can provide better balance and propulsion.
The contours of this anatomical last are smooth and rounded, to more closely follow the shape of the human foot. Footwear built on this last wrap the foot better, especially the heel and bottom of the foot, for a more comfortable, ergonomic fit.
A two-part system for superior shock absorption. The midsole dampens ground impact while the internal shock absorber dampens heel impact. The combined result is enhanced cushioning and less fatigue. The inner layer is more anatomical in the heel and underfoot areas to help reduce foot movement within the shoe, adding greater comfort and stability overall.
Shoes engineered with GORE-TEX® Insulated Comfort product technology are designed for outdoor use in rain, snow and cold conditions. They combine durable waterproofness and optimized breathability with insulation for use in cold weather conditions, which makes them an ideal solution for a wide range of outdoor activities.
