How I choose the correct size?
All climbing shoe models fit differently. We put together our 'shoeculator' to help you find the right size in a new model, compared to your old climbing shoes or street shoes.

Climbing Shoe
Street Shoe
This sizing advice is based on two pairs of brand new shoes. Leather shoes tend to stretch more than synthetic shoes. When switching from synthetic to leather you may want to select a smaller size.
Constructed with a premium quality split leather upper and a fast and secure triple strap closure, the Boreal Silex fits a wide range of foot shapes, thanks to its wide fastening area, that allows for a further degree of adjustment.
Boasting a semi-flat last, the Silex features a stiff midsole with a concaved forefoot, that helps to enhance support and subtly position the toes into a more powerful shape.
With its build of recycled Eco rubber and top-notch sticky Zenith Quattro on the forefoot and heel provides superb traction and purchase.
Long established as a 'go-to' for comfort on long routes, the Boreal Silex's latest updates assure the perfect blend of fit, support, and comfort making it an ideal choice for anyone who wants performance without sacrificing their toes.
