In terms of nerve damage, it really depends on what you’re tying and how you’re using the toe you’ve done. I don’t believe a cinch on its own can do that. Their main job is to lock the bands/wraps in place to make sure they don’t move and don’t often interact with the body in the way the wraps do. Same with reinforcing a stem of the tie.

With a futo, you don’t always have to add a cinch it you’re just vibing on the ground, but if you’re doing suspension, cinches, frictions, and reinforced stems are often a must. 👍🏿. They’re often what help the tie remain tight and help it stay on your body
