Alpinestars Tech 10 Supervented Adult Off-Road Boots
The benchmark boot in Motocross, the Tech 10 Supervented boot further advances the innovations that make it the most technical motocross boot ever. Featuring two inlet ports on the front, a ventilated shinplate, perforated padding and extensive mesh sections, the Tech 10 Supervented has been designed for maximum airflow through the boot's front and effective heat exchange. The new mesh inner bootie boasts a 3D Higher Spring insole which uses air channels within the sole for optimal levels of ventilation, while also creating a cushioning effect for enhanced levels of comfort. There is also a new sole with an extended honeycomb design for superior grip and feel on the bike's pegs, especially in wet and muddy conditions.
