Customize your Korkers configuration with this 10-pack of Aluminum Bars. Whether you choose to combine some of them with carbide spikes or line your entire sole with aluminum bars, these will add traction to your current sole. These bars are constructed from a softer aluminum which morphs as rocks bite into it—providing plenty of grip as you wade through strong currents. This set is compatible with any of the Korkers Triple Threat Sole System soles, so you can change them as you travel to waters with different underfoot conditions.
