If you've ever been termed an ‘outdoor fanatic’, prone to attacking mountains and rugged terrain with insane and intense athletic zeal, then US sock makers Thorlo are on your side. Their new 2017 range includes these colourful Thorlos Outdoor Fanatic Walking Socks, designed and tested to reduce pressure, friction, moisture and pain during speed hiking, trail running, peak bagging and even canyoneering. The socks use venting panels and performance fabrics, with PrimaLoft, a yarn blend of merino wool and siliconised polyester for outstanding insulation, wicking, softness and durability, plus the addition of copper ion technology for odour reduction and its anti-fungal properties. The state-of-the-art socks in the entire Thorlos Outdoor collection is designed for optimal foot protection and performance. These particular Thorlos Outdoor Fanatic Walking Socks have form-fitting compression-grade arch and ankle support to protect tendons and plantar fascia, with impact-reducing, non-bulky loop padding, and sculpted and contoured light padding for the ankle bones. No-rub hand linked toes for smooth seams help prevent blisters - important particularly during intense activity in close-fitting footwear.
