DS (14 months) has been walking independently for 10 weeks, rarely falls and only crawls when he's trying to get under something. He's ready for shoes but we can't find anything that fits. He has a high arch (middle bit of foot), we're abroad so shoe shops only measure length and not width and shoes will not go on. DH had similar feet when small and they flattened out but DS'll need shoes before then!
He's been wearing socks with a base type thing but they're too thin for outdoors now it's getting colder. We got him some sheepskin slipper boots which seem to keep his feet warm and dry whilst walking outside (when cold and damp but not wet) but does anyone have recommendations for proper waterproof shoes for winter? We're in the UK in December so should I wait and take him to clarks/independant or is there anywhere online?
