So far the only shoes I've found that fit my large and wide feet (with narrow ankles). I wear them for training, walking and everyday life. They are good in both summer and winter. I usually have to walk in very wide shoes, but with these shoes, the regular (D) width is comfortable - you only need to wear them for a day or two to break them in and then they are GREAT. That's my experience, but I think every foot is different. Not everyone has wide, uncomfortable feet like me.
