Both DD and DS have E fitting feet - very narrow and not particularly common.
Anyway, their feet grow quickly so their shoes, whilst worn, are not worn out and I would still be happy for them to wear them if they still fitted. I usually put them in the charity shop because they are not good enough for eBay. But then I think of someone buying them and putting them on their child and them not fitting - the E width will have rubbed off and all you can see on the sole is the length size so they will be way too narrow for the majority of children. I don't shop in charity shops myself due to these "outsize" issues - am 6ft and I always think that people who shop in chartiy shops are a sort of normalish size. I would never be able to get children's shoes in a charity shop for myself as their feet are too skinny so I can't see anyone else looking for E fittings in there either.
What shall I do with them?? - I currently have a pair of black boys shoes size 10.5E and a pair of baby girls pink shoes size 3E. Both have been outgrown but I feel I shouldn't put them in the charity shop.
