Bottom line

When it comes to bouldering performance, the Mutant is simply remarkable. It is also quite an enamoring Boreal product in the areas of surface traction and comfort.

-The Boreal Mutant is built for senders who wish to accomplish complicated routes using a variety of climbing techniques. Its engineering allows users to smear, edge, heel hook, and toe hook with efficiency.

-It comes built with Lateral Torsion System—a technology that puts a tensioned rand around the medial zone of the shoe for extra midfoot support (especially on holds smaller than usual). It also improves the shoe’s level of sensitivity and flexibility.

Downturn. The Mutant belongs to Boreal’s selection of aggressively downturned climbing shoes. Its finely edged front contact point permits owners to tiptoe their way on tiny projections with as much strength and precision as possible.

Applications. This aggressive rock climbing shoe from Boreal is intended for sport climbing and bouldering (whether indoors or outdoors). It has a set of features that capacitates its wearers to take on overhanging terrain.

The Boreal Mutant is a low-cut climbing shoe. It is built on a highly asymmetric last, making its interior heavily curved. Its leather upper might stretch with repeated use of the shoe. Since it is a unisex gear, female climbers may need to go down a full size to achieve a comfy fit. The snugness of its arch zone is thanks to the Lateral Torsion System. Its Velcro closure provides a secure and personalized lockdown.

Midsole. This shoe built for bouldering has a midsole unit for extra underfoot stiffness and support. It is engineered with an anti-deformation technology which allows it to flex without bending out of shape.

Outsole. A Boreal-exclusive outsole called Zenith is the component that provides adequate grip on different kinds of terrain in the Mutant. When it comes to thickness, it can be anywhere between 4 mm and 4.5 mm, depending on the shoe size bought. This type of outsole favors edges and similar surfaces.

The climber’s foot is safely tucked inside the Boreal Mutant’s split leather upper. It comes with no liner. Virtually every inch of its lower region is reinforced with a long-wearing rand to grant the user extra clinging power where needed. The dome of its forefoot is furnished with Friction Skin, a special rubber coating around the toe box that gives the wearer additional grip when toe hooking. Stitched to its heel are two pull loops to assist during on and off. An adjustable Velcro strap makes up its closure system.
