I wear a size 12 medium width in a regular shoe, but these are just about right in an 11. They are the best that I have had for working in the garden, the garage/wood shop and even to the grocery store. They feel very comfortable on hard surfaces like concrete and tile, but are equally good for the garden in north Florida where we have sand instead of true soil because they can be rinsed out with the hose quire easily and there is no worry about them growing mildewy. The tread, I find gives good traction on wet surfaces and does not hold sand, dirt soil etc, but washes easily. Because they feel about a 1/4 size bigger than I like I can wear a pair of socks and the fit is perfect. I expect to replace these when and if the time comes with another identical pair.
