My NB307's are giving me grief. Too narrow across the toe box or something and squeezing/rubbing my left toe. (Right side is fine.) Thought it was my orthotics, took them out, didn't help, still too tight. Anyone else have similar problems? Do I just have to suck it up and get a different pair of shoes? These felt fine in the store, so I'm leary about trusting my judgment right now. :[
