AKU Tengu GTX £300

This B2-rated, 4-season boot ticks all of the boxes for winter use: it’s rigid, stable, waterproof, grippy and built with high-quality Italian craftsmanship. More so than other boots, it has quite a climbing-focused style, with a precise fit that delivers a better feel underfoot and improved footing over rugged terrain.

Tacky traction courtesy of the Vibram Curcuma outsole with climbing zone further enhances grip. Structurally, the Tengu GTX is rock-solid stiff with only the slightest bit of flex. It’s made up of a dual-density PU midsole with a carbon fibre shank, while the upper is pretty tough with a high-ankle cuff, internal gaiter and padded tongue. A strong toe box, wraparound rand and rigid heel counter complete the burly design.

Comfort is surprisingly decent, considering the stiffness of the boot, but ultimately this boot isn’t for general hillwalking – it’s all about reassuringly stable and precise footing on snow and ice. The fit is relatively narrow.

IF WE’RE BEING FUSSY

The relatively long and narrow fit might not suit all foot shapes, so it’s best to try before you buy.

They are colder than others, due to a lack of insulation, and the extremely stiff sole isn’t the comfiest for walking. Despite being unisex, there isn’t a women’s specific model.

Verdict

A technical, well-engineered, B2-rated boot for wintry adventures – but it might be too stiff for some.
