Alright you thrifty/frugal shoppers (shoes for DD)

battybtags

I've decided that DD needs both inside and outside shoes that can get trashed at daycare. The playground gets very muddy and her winter boots & snow pants were covered in mud when she came home yesterday. I'm thinking ahead to nicer weather and I don't want her good sneakers (from SR) to get ruined outside. So...I'm looking for a pair of sneakers for outdoors and something else she can wear inside (slippers, robeez, etc) there in case they take off her muddy shoes. Something cheap b/c I don't want to care if they're destroyed. Any ideas?  Or if anyone has any  hand-me-downs, let me know!
