I'm debating getting a pair when my current running shoes are worn out. I don't run regularly (I go to the West Jax Crossfit) and we have a couple guys there that swear by them. My running form has always sucked (I shuffle as opposed to the figure 4 technique) and I know I would like something to have on my feet when I'm doing heavy lifting (I just do things like the crossfit total in my socks now), but how does it work with other activities besides running/lifting? Is doing things like box jumps going to hurt like hell only wearing the five fingers vice a running shoe?
