I have a checkered history when it comes to ‘walking’ boots. My general motto has been to avoid them whenever possible, opting for trail shoes since a pair of saturated, old, cheap, leather tramping boots savaged my feet back in 2013.
Overall this is a great device—much more durable than an all-aluminium device with no significant weight penalty and good performance at around the same price point as the rest of them. If you find yourself replacing belay devices frequently, then this is worth checking out.
