People said these ran narrow but they don't really provide 1W, only 3W... So we went that option and boy is it roomy. Wanted to be able to wear all those fluffy and thick socks in winter, but now he MUST wear all those thick socks or it's too wide and floppy. Aside from the width - we bought proper arch support insoles for better wear (and a slightly damaged foot) and sno-seal as this place is rainy, ice-rainy and a little sleety in winter. They had a lovely matt finish before, now black and shiny but no matter, they still look good to me.
