Most of the discomfort from crutches comes down to two things: the handle and the height. The Harmony's handles are shaped to sit flat under your palm rather than round like a broom handle, so your wrist stays close to its natural angle instead of bending back against a bar. Get the height wrong and that discomfort moves up into your shoulders and back, so these adjust from 95cm to 118cm using a spring button pin and a locking collar, letting you set the handgrip level with your wrist bone in a couple of movements.

The open-cuff design is the other main difference from a standard crutch. Instead of a closed loop you push your whole arm through, the semi-open cuff lets you slide your forearm in and out from the side, while still sitting just below the elbow for solid support. It's a small change that matters most on the days you're taking the crutches on and off a dozen times.

Underneath the pink finish is an aluminium frame that keeps the pair very lightweight at less than a 1kg total,  while still holding up to 100kg of weight. Assembly is minimal – the ferrules and handles are ready to go out of the box, and setting the height is quick and easy.
