How to Choose the Right Mountaineering Boot

Sizing and Fit

To ensure the best fit, measure your feet accurately using a sizing chart or guide. It’s recommended to measure your feet at the end of the day when they are at their largest. When fitting mountaineering boots, wear the socks you intend to use while climbing. Consider using orthotics for additional support and comfort.

Features to Consider

When choosing mountaineering boots, consider factors like the level of insulation needed for your typical climbing environments, the compatibility with crampons, the design of the cuff for ankle support, and the overall weight of the boot. Assess these features based on the type of climbing you do and the conditions you’ll be facing. For example, high-altitude mountaineering will require more insulation than a summer rock climb.

Caring for Your AKU Hayatsuki GTX Boots

Cleaning and Maintenance

1. Remove dirt and debris with a soft brush or cloth.
2. Wash the boots with lukewarm water and mild soap if necessary, avoiding harsh chemicals.
3. Apply a waterproofing treatment regularly to maintain water resistance.
4. Store the boots in a cool, dry place away from direct sunlight and allow them to dry completely after each use.

Repair and Replacement

Inspect your boots regularly for wear and tear. Replace worn laces promptly. For more significant damage, such as sole separation or upper tears, seek professional repair. Replacement of components, such as the outsole, is often possible to extend the life of your boots.
