Don't even try to measure your insole, you'll never get it right. Just look at the measurements on any of your sneakers in CM or CHN. Then take that information and find the corresponding US size in the size guide. For example, the insole length of 25 CM corresponds to US 7 in Vans. You may get a different US size with a different brand due to slightly different measuring.
The year was 1877 when the seaman Helly Juell Hansen decided that he no longer wanted to get wet helplessly on the ship. But if he did not want to succumb to the bleak Nordic weather, he had to come up with something good. And that's what happened! Helly and his wife set up a company producing waterproof uppers to keep you warm, even if the weather's not perfect. Today you can see the logo of the brand not only on professional athletes, but also those who simply want to feel comfortable, and not only during outdoor activities. Products of the brand perfectly combine their outdoor legacy with a design that is tailored to the city.
