Aside from having a usefulness in easy removal, if that has interest to you, there are three situations where hook and loop (Velcro) might make sense.
- If your shoe sole is not very flat width-wise, length-wise, or both
- The sole has aggressive/deep tread or void areas that make for less surface area to bond to
- You are bigger and put a lot of torque/twisting on your sliding shoe while walking or sweeping with a gripper on it.
Hook and loop attached sliders will allow for more difficult soles to be converted, and will be more durable under heavy use.
