The Boulder X mid shoes from La Sportiva are excellent especially for technical terrain and via ferrata. These shoes are inspired by the legendary climbing project Mythos. The water resistance of the Gore-Tex® Extended membrane ensures that the rubber pads reliably protect the shoe from abrasion. The patented lacing evenly tightens these shoes, including the heel part. The shoes are very comfortable, so they are also one of the most popular models of the La Sportiva brand.
