Keen Rover Crib Boot 18 mo

Keen Rover Crib Boot 18 mo Color blue and lime green Warm and cute and they stay on. My daughter wore them from age 7 mo to 15 mo . She was a size 3-3.5. They fit great, even with warm socks on and her feet were always toasty. They are in mint condition. Keen size charts say they fit 11.4cm feet. She is a size 4 now and they don’t fit, so I think they run small.
