Mammut's new Merlon GTX mountain boot - Vibram sole, Gore-Tex lining and precision-enhancing lacing technologies - £180

New for spring 2013 is this fella, the Mammut Merlon GTX, a lightweight mountain boot aimed squarely at scramblers, mountain walkers, and potentially, anyone looking for a light-ish crampon-compatible boot we reckon.

The new boot - available shortly - combines nubuck and synthetic leather for the uppers, it says here, and has two technologies designed to improve fit and give better precision. First there's something called Base Fit technology which anchors the lacing points to the sole giving a snugger all-round fit.

Second, asymmetric lacing is designed to work with the foot's shape to throw weight and emphasis onto the big toe and increase precision as a result. To help with that, the Vibram Maton sole unit includes a smooth Climbing Zone section under the big toe area making it ideal for edging while climbing or scrambling.

Weight is kept down with a lightweight cushioning Poro wedge in the mid-sole, a Gore-Tex liner is there to keep your feet dry and there's an al-round rubber rand to protect the uppers from abrasion when either kicking into snow or stoming through rubble.

All in all, looks like an interesting mountain all-rounder that should cope with everything from scrambling and via ferrata, through technical mountain walking and possibly through to lightweight crampon use. We'll know more once the boot actually arrives some time in the next couple of months.

It seems to have a lot in common with the current Mt Centry and Mt Centrina GTX alpine boots with which it shares sole and upper technologies.

Retail price is around £180. More about Mammut at
