Well they are one of the wider foot beds/ treads on the market right now. I have size 12's and a pretty wide foot and they are nice and comfy on me. If not, I know that Solomon makes wide boots, but I dunno if you want to go that rout. As soo as you heat mould them, they will conform perfectly. But the Lashed are pretty wide as is, so unless you have rediculously wide feet then you are good to go. Hope this helps bro
