The upper is made of an ultra-lightweight and breathable material, which reduces the weight significantly while maintaining protection and comfort.
ALTRA originated in Utah, USA. All ALTRA trail running shoes were traditionally named after the mountains in Utah. Now 10 years later, it finally broke this tradition and picked the iconic Mont Blanc, Europe's highest peak.
