Updates to Boreal Spider

  • The slip-lasted Boreal Spider is a durable piece engineered to provide enough climbing precision on rocky routes and wall-type surfaces. Its designers gave it a fresh new look and a sleeker profile overall.
  • It is crafted with IRS or Integrated Rand System. This one-piece sole technology bolsters the durability of the shoe by reinforcing the lower perimeter of the shoe, including the outsole.


Downturn. The Boreal Spider is a moderately downturned climbing shoe. It has a kind of forefoot zone that pushes the foot forward, allowing users to pull off a wide range of techniques on a variety of terrain features with relative ease. Moderate rock shoes are comfortable enough for extended (multi-pitch) projects.

Applications. This beginner-friendly shoe from Boreal is built for sport climbers. It promises an all-around kind of performance, whether indoors or outdoors.


The Boreal Spider is a rock climbing piece with a low-cut cuff. As a unisex shoe, female climbers may need to go down a full size to get a precise fit in it. It has a curved or asymmetric interior. Its leather upper might stretch with repeated use of the shoe.

A customized and secure fit may be achieved with the Ankle Lacing System (ALS). This Boreal-exclusive technology also locks the heel in place, thanks to its heel-hugging ankle-to-eyelet lacing scheme.


Midsole. The Boreal Spider comes with an anatomically engineered midsole to allow wearers to mount on ledges and other projections with as much support and underfoot protection as possible. It only covers half of the shoe’s underside.

Outsole. With the Boreal Spider’s FS-Quattro outsole, users can ascend their favorite wall or rock with sufficient surface grip. It is built to withstand abrasive hazards and a wide range of temperatures. Its thickness varies—it can be anywhere between 4 mm and 4.5 mm, depending on the size of the shoe.


The Boreal Spider’s below-the-ankle upper is made with a combination of split leather and Lorica fabric. Its inner walls are lined with canvas. Extra in-shoe comfort is courtesy of the shoe’s padded tongue. Its rubber rand, a one-piece construction, delivers extra climbing security and scuff protection at the same time. A pair of pull loops are attached securely to its heel to help users get in and out of the shoe more conveniently.

Rounding out all things upper in the Spider is the Ankle Lacing System. This proprietary fit management system consists of synthetic looped bands for eyelets and a round lace made of interwoven cords.

I am passionate about maintaining an active lifestyle. I’ve been running and playing tennis since high school. In the last 5 years, I’ve picked up weight lifting and bouldering as part of my regular fitness routine. You can usually find me hitting the weights or rock walls at the gym, or trying out a new sport.
