Finding Your Sole

Rubber matters!  Stack the odds in your favour by choosing a sole that suits your style of climbing or bouldering.

We offer a large selection of compounds and thicknesses to choose from:

  • Five Ten Stealth C4 (3.5 mm)

  • Vibram Grip (3.5 mm)

  • Vibram Grip (5.0 mm) (+$5 per pair)

  • Vibram XS Grip (4.0 mm) (+$5 per pair)

  • Vibram XS Grip 2 (4.0 mm) (+$5 per pair)

  • Vibram XS Edge (4.0 mm) (+$5 per pair)

So which rubber is best?     …all of them, but for different situations.

Before choosing a rubber, we recommend considering how each of the following points will affect your climbing:

  • Softer rubbers (e.g. XS Grip 2, XS Grip) tend to provide better grip on overhanging terrain, slopers, and slippery holds or slippery rock.

  • Harder rubbers (Stealth C4, XS Edge) tend to provide better grip on very small footholds and edges, especially on vertical terrain.  They also tend to provide more durability.

  • Thinner rubbers will provide more sensitivity, and excel on overhangs and slopers, but will come with a loss of durability.

  • Thicker rubbers will provide more stiffness, and help with edgeing on vertical terrain with small footholds and edges.  They will offer more durability than their thinner counterparts

  • Light climbers should generally aim for softer rubbers and avoid 5.0 mm thicknesses, while heavier climbers should consider the harder compounds and medium to high thickness.

A note on sensitivity and stiffness:
Shoes with a very stiff midsole and structure will not see the same sensitivity change from different sole thicknesses or compounds.  For example, putting a 4.0 mm sole on a pair of La Sportiva Tarantulas (originally 5.0 mm) would have an undramatic effect on sensitivity because the shoes have a very stiff midsole, so the total stiffness of the shoe is not as heavily dependant on the sole.   However, a soft shoe like a Python or a Moccasym will be heavily affected by sole thickness and compound, because the sole is the main contributor to stiffness.
