REVIEW
"I chose RAYVE LAHTI boots for my youngest son to wear to nursery and they've been brilliant – grass, forest, tarmac and damp autumn weather. The sheep wool lining keeps his feet beautifully warm without sweating, and the waterproof membrane handles wet conditions too. They fit his wider foot and higher instep well, and thanks to the velcro fastening he puts them on completely independently at nursery. Plus they look really stylish, so I'm already considering them for my two older children. I'd definitely recommend them to any parent looking for comfortable winter boots for an active child."
