Shoe Size Conversion
This comparision chart will help you determine your approximate size. Shoe sizes are not consistant within brands, styles, or even different models from season to season, so use this chart as a guide only. Everyone's feet are very different and factors such as width, volume, and shape can have a substantial impact on what size you will wear in any given model. Consider that many casual shoes can sometimes be a up to a full size smaller than athletic shoes.

Shoe Widths: What do they mean?
Many footwear models, primarily in the Running category, are available in different widths. Like shoe size, this is not an exact measurement, but an expression of the different width options within a given model. In Men's Running Footwear, a D width is considered regular, and in Women's a B is regular. If a model on our website is listed as being available in a D width (men's) it doesn't necessarily mean that the model is offered in different widths. There may be only a regular width available. Check out the chart below for an explanation of what the different letters mean pertaining to shoe width.
