My bf is tall and has big feet . weighs just over 200 pounds… these fit him pretty comfortably, so much so that he accidentally wore the 1st pair outside.I bought him another pair so he can have an inside pair and continue to use the 1st pair as outside shoes.The 1st pair still maintains the thickness/support and sturdiness and this is after about 9 months of wear outside (taking out the trash, lifting boxes, etc.)
