If you can find the right sized shoe, these are great.  I got one size too big so I have to wear socks otherwise the back of my heel rubs inside and bleeds.  I just use these now for the snow because the traction is superb on them.  I have snug fitting five fingers that I use on the other days.  Ease into these, it's like starting over running.  But once you get used to running minimal, it's the best feeling ever.  Highly recommend these but make sure you get the right size.  I wear size 13 in shoes and got these in 13 when I should have gotten 12.  If your a 13 size in men's shoes, get the 46 in vibram shoes to get a good fit.
