Trail Shoes
Rocky alpine terrain demands aggressive grip. Inov-8 excels here. Decathlon's MT2 offers similar traction at a lower price point.
Hydration Vest
Essential for carrying water and nutrition. Salomon vests are popular for good reason, but Decathlon's alternatives do the job at half the price.
Trekking Poles
Trekking poles save energy on big climbs. Collapsible aluminium poles work well for most runners.
