The Ultra light / Race models are made to run uphill as fast as possible and are therefore ideal for competitions. The range of motion during the ascent is very generous and the weight is minimal. Although the use of materials such as carbon makes the shoes as stiff as possible, the Ultra light models perform less well during the descent. The weight is between 500 and 850 grams.
