Don’t bother measuring your insole you’ll never get it exactly right. Instead, check the measurements in cm or CHN on any of your sneakers. Use that info to find the corresponding US size in the size guide. For example, a 25 cm insole length corresponds to a US 7 in Vans. Keep in mind, sizes may vary slightly between brands due to different measuring methods.
If you choose the wrong size
We’d be happy to exchange it for you.

Altra is an innovative brand for runners looking for comfort and footwear that supports natural movement. It was founded in 2009 in Utah by a group of running enthusiasts who decided to create a shoe that respects the healthy natural biomechanics of the foot. A distinguishing feature is the FootShape™ Toe Box, which is a wider space for the toes to spread out and spread naturally. This helps to improve stability and reduce the risk of injury. Another key feature is Balanced Cushioning™ with Zero Drop™, which aligns the heel and toe into one plane. This promotes proper posture and a natural running style. These technologies make the Altra shoes especially popular among professional trail runners and ultramarathoners. However, recreational runners or fans of outdoor activities will also find them to their liking. Well-known ambassadors and fans include ultramarathoners such as Zach Bitter, world record holder in the 100-mile race, and Jason Schlarb, winner of the Hardrock 100. You couldn't look harder for proof of quality. Premium materials, maximum comfort and functionality make these shoes a great choice for professional and recreational runners around the world. With every pair you get comfort, performance and innovation to support your healthy and active lifestyle.
