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. Everyones's feet are very different and factors such as width, volume, 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.

Running Shoe Categories: Why are they necessary and how do I choose?



The right tools for the job


Running footwear is purpose built to provide maximum shock absorbtion with minimal weight, and to correct or prevent over and underpronation that can cause lasting injuries if ignored.

Your feet are unique!


Running shoes should be selected based on your the type of feet you have, and your unique biomechanic characteristics; meaning... what works for your friends may not be best for you.

What kind of feet do you have?


Our footwear meter can help take some of the guess work out of selecting a running shoe. As a general guide, the shape of your arch determines the characteristics of your feet. If you know which arch type you have then you're one step closer to selecting the right footwear.

Trail Running and Adventure


The Trail category is home to footwear purposely built for off road performance. Adventure Racing, Trail Running, and Ultra Running are sports that often present tougher than usual underfoot conditions and require footwear that's up to the task when plain old running shoes just won't cut it. Outsoles have aggressive, directional lug patterns and provide traction on slippery and uneven terrain, as well as improving climbing ability and descent control. Midsoles are firmer for greater durability and protection, and commonly offer integrated protection plates that provide "push-through" protection from sharp rocks or roots and enhance torsional stiffness. Uppers are either highly breathable or Water Resistant/Proof and are designed to be extra tough but drain and dry fast.
