I'm not a fan of keeping an aider stuck on my boot. I want to be able to kick the thing off my foot if SHTF.
Does this aider function well with the foot loop opened up and taking your boot in and out of it with each step?
I think so. I have the 3 step version, same step design and your foot comes out easily.
My issues with the 3 step is that it is hard to find the steps in the dark while descending. Even during the day the steps can be difficult and kick out. I'll give mine 2-3 more tries and sell if I cannot get comfortable.
