shoe size?

just curious what size shoes your January babes are wearing? Olivia is starting to outgrow her size 3 sandals (partly bc they got stretched out in a lake) but it has been a real pain to try to find velcro sandals in size 4! walmart had the same style she had before but the velcro would be ideal since I know we'll be getting them wet again before the end of summer 😏 also anyone else have a babe with CRAZY sweaty feet? she can wear sneakers for like 10min and her socks will be soaked through with sweat! I've never seen a toddler with such sweaty feet! 😝
