Boots ideal for dog walking, gardening etc. Adult Size 4/6 (South Croydon CR2)

My son is now 42, he had these when he was about 12 and a shoe size 4, when they were quite trendy. He went off them and out of curiosity I tried them on (size 6), they fitted, were comfortable and looked great with jeans. Unbelievably, apart from some scuff marks on the tops, they show no signs of wear, even on the soles. They've been stored in a basket in my bedroom for around 20 years now, I can't bring myself to just throw them away if someone else can find a use for them. As I say, ideal for messy tasks or dog walking, no need to worry about ruining them!
