This may seem like a silly question - I am planning to buy a pair of KSOs each, for myself and my husband. I already have unusually wide feet (probably due to years of running around barefoot), and I find it difficult wearing normal boots or shoes, as the width always falls short. My concern is - will wearing these "barefoot" shoes for running cause my feet to splay further? Will my feet get wider (I'm 30 years old, so unsure if there will be any changes to my anatomy after this age)? Just wondering if any veteran users of these "shoes" have noticed a change of width of their feet? I just want to make sure before I purchase these, so I don't end up with extra wide feet and have to stare longingly at those sexy dress shoes *sigh*. Any help will really be appreciated. Thanks.
