When you buy a climbing shoe it is necessary to take into account some considerations:
Climbing Performance As you are a beginner and you are searching for a moderate performance to progress very quickly, or you are a veteran climber searching for ultra-performance climbing shoes.
Climbing Activity As you prefer outdoor or indoor, boulder, alpine climbing, the climbing shoe needs to respond to specific characteristics in terms of size and material.
Shoe Fit The foot shape, the material of the footwear, and the shoe closure are the main features to consider obtaining the best fit, as the climbing shoe is the only filter between you and the rock.
