Approach shoes are designed for routes to climbing walls or across rough terrain where ordinary hiking boots would be too bulky and climbing shoes too uncomfortable and unprotective. They are sturdy, offer good grip and are generally fitted with rigid midsoles to withstand passages over rocks or uneven terrain. Their outsoles are often fitted with grippy rubber, similar to that used in climbing shoes, for better traction on rocky surfaces.
Grip is of paramount importance when choosing an approach shoe. The sole should be made of hard-wearing rubber with a lug pattern suitable for both trail walking and rock climbing. Sensitivity, or the shoe's ability to transmit the sensations of the terrain to the foot, is also crucial for technical passages where precise foot placement is required.
For long approaches, comfort is essential. A good approach shoe must adapt perfectly to the shape of the foot, with enough space for the toes, but not too much to avoid chafing and blisters. The choice of size is therefore critical, and it's often advisable to try them on at the end of the day, when feet are slightly swollen.
Construction materials must be both lightweight and durable. Leather and synthetic textiles are common, each offering a different balance between durability, breathability and water resistance. Rubber reinforcements on high-wear areas, such as the toe and heel, extend the life of the shoe.
Some models are specifically designed for particular types of terrain or weather conditions. For example, models with a waterproof lining may be preferable in wet environments, while others with increased ventilation are better suited to hot, dry conditions.
Weight is an important factor, especially for long approaches and climbs where every gram counts. Lighter shoes reduce fatigue, but it's essential not to compromise protection and performance for lightness.
The lacing system can vary considerably from one model to another. Laces that extend to the toe of the shoe enable a more precise fit, essential for technical climbing.
Once you've chosen your approach shoes, proper care can extend their life. Regularly clean off mud and debris, and air-dry them away from sources of direct heat. Using a waterproofing agent suited to the type of material can help maintain water resistance.
Approach shoes are a compromise between the performance of climbing shoes and the comfort of hiking boots, making them indispensable for mixed mountain routes. By taking into account grip, comfort, durability, versatility, weight and lacing system, you can choose the pair that best suits your mountaineering and climbing activities. Be sure to try them out with technical socks and test them in conditions similar to those you'll encounter in the field for a complete evaluation.
