Find your clothing size using this chart: All measurements should be taken under, not over, clothing. All measurements refer to body size, not garment size. (Men's - Multiply cetimeters by .39 = inches), (Women's - Multiply inches by 2.54 = centimeters).

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.

Review a Running Category below

To learn more about the attributes of that foot type and how that type of shoe can help you achieve your running goals.

Neutral Cushion

Neutral Cushion footwear offers maximum shock absorption and flexibility. This category of footwear varies between very light offerings that provide maximum flexibility and speed to more robust models that are more durable and slightly stiffer for higher mileage training. Cushion footwear are best suited for runners that have a neutral gait or underpronate.

Stable Cushion

Models in the Stable Cushion category offer excellent cushioning and some medial support they are more flexible than stability footwear. Stable Cushioning shoes are best suited for runners that have mild or no overpronation and runners willing to give up some durability for more flexibility.


Stability footwear offers a good blend of cushioning, medial support and durability. Stability footwear often have some form of medial posting, and are generally firmer for increased durability in the midsole. Stability footwear is best suited to runner's that need moderate motion control and prefer a firmer more durable shoe.

Motion Control

Motion Control footwear offers the most support and durability out of the four footwear categories. This type of footwear is designed to limit over pronation (or slow the rate at which a runner overpronates). They are generally heavier but very durable. Motion Control footwear is best suited for runners that have severe overpronation.

Form Improvement

Models in this category are suitable for all foot types, providing that you adopt a mid-foot style of running (also know as Pose or Chi Running). Essentially, by not landing on your heel you switch your body from using pronation as it's primary means of shock absorbtion, to developing muscles in your lower body to absorb impact. You should thouroughly investigate the topic to determine whether you are a good candidate for this style of Running.

Road Racing

The Road Racing category houses some of the fastest and lightest models in our selection. Weight reduction is paramount so durability and support are often compromised in favour of flexibility and reduced weight. They are best suited for racing, speed work, or any other training that is short in duration and distance, or less frequent. Models in this category can reside in either the Neutral Cushion or sometimes Stable Cushion categories although they are a lot lighter and therefore a lot less durable.

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.
