Slim Fit Last

The Slim Fit Last (SFL) is a specially developed last shape designed to fit the contours of lower volume, narrower feet.

Climbing shoes are performance products, and rely on a good fit to optimize this performance. Many climbers find that conventional shoes do not provide the fit they need, and for this reason Boreal developed a new last. Featuring a narrower, lower volume shape, the Slim Fit Last (SFL) was specifically designed to provide a secure fit for slimmer footed climbers.


Zenith is a unique high performance climbing rubber compound developed by Boreal. This compound provides outstanding friction and excellent hold on small edges.

Zenith rubber is a high performance rubber developed by Boreal. Zenith is designed for no-compromise performance, and features incredible friction properties combined with an ability to hold micro edges. This ultimate compound is featured on our highest performance rock shoe models.
