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

Altra is an innovative brand designed for runners who prioritize comfort and footwear that supports natural movement. Founded in 2009 in Utah by a group of running enthusiasts, Altra set out to create a shoe that respects the natural biomechanics of the foot. A standout feature is the FootShape™ Toe Box, which provides extra room for the toes to spread naturally, improving stability and reducing the risk of injury. Another key innovation is the Balanced Cushioning™ with Zero Drop™, aligning the heel and toe on the same plane. This design promotes proper posture and a natural running form. These technologies have made Altra shoes especially popular among professional trail runners and ultramarathoners, but they are equally well-suited for recreational runners and outdoor enthusiasts. Notable ambassadors include ultramarathoners like Zach Bitter, world record holder for the 100-mile race, and Jason Schlarb, winner of the Hardrock 100, proof of the brand’s exceptional quality. With premium materials, unmatched comfort, and cutting-edge functionality, Altra shoes are a top choice for both professional and recreational runners worldwide. Every pair offers comfort, performance, and innovation to support a healthy, active lifestyle.
