Boreal Silex Climbing Shoe

The Boreal Silex is a ‘go-to’ rock shoe for climbing long routes in comfort, offering a perfect blend of fit, support and precision; ideal for those climbing in the mid grades to push their skills in comfort.

Constructed with a premium quality split leather upper and a fast and secure triple strap closure, the wide fastening area allows a further degree of adjustment for a strap closure shoe, to help accommodate a wide variety of foot shapes. This semi-flat lasted shoe incorporates a stiff midsole with concaved forefoot, that enhances support and places the toes into a subtly more powerful position. The sole unit features a large section of Boreal's recycled Eco rubber, while sticky Zenith Quattro is used in the climbing zones at forefoot and heel.

  • Designed for day long use indoors or outdoors. Perfect for long crag days, multi-pitch climbs and extended training sessions

  • Sticky yet durable Boreal ZENITH Quattro outsole. 4-4.5 mm thickness depending on size.
  • Middle part of the outsole with recycled rubber

Redirection of your order once despatched
