The light and flexible Keen NXIS EVO Waterproof Boot is fantastic on long days.
The Keen NXIS EVO Waterproof Boot is a boot that’s on the trail shoe end of the spectrum, with a light and flexible construction, they do have enough solidity to retain a boot-like feel.
The upper is synthetic mesh with reinforcing overlays, a big toe bumper and a plastic cradle around the heel, which has channels through it containing a thin cord, placed under tension when the boot is laced, since the cord also runs through a lace hook on either side.
As I’ve worn them in, the cord moves a little more when I tighten the laces, so seems to be adding tension and retaining the heel/ankle shape. The padded ankle cuff has an internal patch labelled Heel Lock.
It abraded of my socks, and it’s unnecessary; if you’re getting heel lift the boot doesn’t fit you, your laces are slack or the boot’s worn out. The fit is excellent, with a fitted heel and wide forefoot: fantastic on long days.
Underfoot there is a good amount of padding, but the midsole isn’t as thick as it looks – most of the grey EVA is external to provide side protection. There’s a nice flex at the forefoot and a firmer flex at the heel, which gives me a good mix of stability and dexterity.
The grip is good, until I get onto mud or wet rock; and the KEEN.DRY waterproof membrane works well with the breathable upper to keep my feet comfy.
