They don't cut into my feet or toes at all. (I suppose that would be an issue if you got a size that was too small) The toes are shaped and sized for each toe, so they don't bag out either. The seams at the big toes are not on the outer edge, which I really appreciate as seams often rub on my big toes because of the way I walk. (the seams are up a little)
Honestly, I wore those socks for 3 days because I like them so much. I LOVE being able to wiggle my toes and use my toes. I did a 10 hr shift on my feet yesterday and my feet weren't bothered by the socks, in fact they felt pretty good by the end of the day.
I think I much prefer the wool socks, but I'm a woolweenie. Injinji also makes cotton toe socks and tabi socks.
My next pair of socks will likely be another pair of Injinji woollies.
