I use the New Balance minimus for my cross training. It's pretty much the same idea as the 5 fingers but with a regular toe box, but wide. My toes don't work in five fingers but I love the minimus for cross training. I think this is the current version of the shoe I have. I didn't realize how much NB had expanded the line until I went to look just now.
