The Alpe d'Huez crew sock is the first of our Climb Series and it’s named after a grueling stage of the Tour de France. In road cycling, this is considered a mythical climb, with 21 switchbacks ascending over 1120 vertical meters in just under 14 kilometers at an average grade of 8%. It’s tough. We figure the Climb is a perfect fit for the QEJA sock. Materials - 50% organic cotton, 35% antimicrobial polyamide–under foot and heel where performance is key, 10% recycled polyester and 5% elastane–for the perfect stretch. A reminder that even if you’re tapping out on the toughest climb of your life, your feet will still be comfortable. Sizing - Please reference our sizing guide to find your best fit, located on each product page. Each case includes 10 pairs - 3 Small, 3 Medium, 2 Large, and 2 X-Large MSRP per pair - $22.00 USD
