DD2 is in Reception and school have waterproofs for wet or muddy play times. We have uniform waterproof dungarees but provide our own wellies. I bought DD new Gymboree wellies in November, she's a slow grower and so they still fit, but they're trashed. She needs new wellies, I don't want to buy the same as last time and would prefer to buy stronger ones that might last longer. Any suggestions? TIA
