I just picked up a pair of Vibram KSOs yesterday but they seem to be giving me some trouble in the short time I've been wearing them. I've been getting chaffing on my left foot, right where my bunion would be if I had one...that little knoby part below your big toe. It seems that with every step I take the little rubber sole part there rubs up and down against my skin....it does not feel good. :(
Is it normal to have to break in Vibram KSOs? Should I just keep slowly wearing them from now and it'll all get better soon? I've been wearing them without socks and I really don't have the money to get toed socks as well....
Yes, I took short walks in them for 2 weeks before I even attempted running in them for any distance. My feet needed to adjust AND a chance to grow back some muscles in my feet that had not been used in many a year.
It depends on your particular foot anatomy. My KSO Treks fit perfectly as soon as I figured out how to get into them and adjust the straps properly. My wife has had to break hers in a bit, but she has oddly long second toes.
Break-in is expected for some people. I'm on my second pair. The first pair needed no braking in (they were KSOs), this pair (KSO Treks, the leather ones) did. Also, Vibrams change the way you walk as you adapt more to barefooting. So some of it might mean developing different muscles, or at least new muscle memory.
