Integrated Rand System

The IRS system goes a step further in the manufacturing of climbing shoes. This one piece climbing sole never deforms and has a superior fit.
We can achieve different thicknesses in the rubber and the one-piece construction increases durability. 


The innovative one-piece sole and rand construction of the Integrated Rand System (IRS) allows Boreal to finely tune the rubber thickness around the shoe for the optimum balance of fit, performance and durability. By combining the rand and sole unit into one piece, there is zero chance of delaminating.
