It is not enough to know that shoes play an essential role in slab climbing; you also have to understand how to choose one.
While there are several considerations to make, here are the most important that will help you narrow your options and get a good one.
The type of rock: One major factor to consider when getting the best slab climbing shoes is the type of rock. You need a shoe with footholds that have small edges when climbing hard or slick rocks like Limestone.
The temperature of the rock: Another factor you need to consider when choosing the best slab climbing shoes is the rock's temperature. If you are climbing slab on a rock with a low temperature, then you can consider getting a rubber shoe.
