The Boreal Silex lace is a reasonably stiff entry to mid level rock climbing shoe, ideal for all day trad climbing and those starting out.

The Silex is based on the last of the classic Boreal Joker but stiffened up to offer maximum support on big routes and all day climbing use. The Silex is perfect for everything from visits to the local climbing wall or a day in the mountains, to a circuit bouldering session with friends. Due to its increased stiffness the Silex may actually be a better bet for novices than the Joker, due to the greater amount of support given to feet unaccustomed to the strain of climbing.

Apart from it’s better looks the major change to the Silex has been the extension of the lacing down to the toe, which provides a much more customisable fit than for the previous model, or for the Joker.

Overall, a very good shoe that comes highly recommended in this class!

Boreal Silex Climbing Shoes

Already have a pair. They are quite a heavy shoe but that is good as it offers support for my large, (size 14), feet. Rubber is a good compromise between durability and stickiness and I have used them for gritstone bouldering, limestone sport and climbing walls. Good shoe.

Boreal Silex Lace

I like them. Beware of sizing! I wear # EUR 48 on the streets. My new Boreal Silex Lace are numbered EUR 49.5 by the manufacturer and are by no means large for me. They fit just perfect. I do not know if this is the case with the large sizes only.
