Tip: there are many styles of sketchers slip ins now. Try on all of them in different sizes and mods (wide, relaxed, etc) before leaving the store. They aren't consistent size across designs.

Apparently your're in MN. Theisens? Fleet Farm? Near me in Iowa, there's a Sketchers outlet.

PS, been there with the compound tib-fib. Freak slip on some ice, not on the bike. Stuff happens.
