Wigwam Named Official Sock of Urban Mudder

May 19, 2015 (Sheboygan, Wisc.) – USA-made performance sock brand Wigwam Mills is pleased to announce a new partnership with the Urban Mudder, the new athletic challenge founded by event organizer Tough Mudder Inc. Currently celebrating its 110th year, Wigwam will serve as Urban Mudder’s Official Sock.

Focused squarely at city dwellers in major metropolitan venues, the series features 5-mile music-filled courses punctuated with 12-15 custom-designed obstacles. Each course encourages athletes to focus on teamwork, personal accomplishment and fun.

“Urban Mudder is a tremendous opportunity for Wigwam to engage with a whole new segment of athletes, enabling them to experience our innovative sock technology,” said Eric Loferski, Vice President of Marketing for Wigwam, “It’s an ideal platform from which to display the performance and comfort qualities that serve as twin foundations of our line.”

Boasting unique construction and cutting-edge materials, the soft and comfortable Urban Mudder signature sock performs to the rigorous standards of top athletes around the globe.

“The Urban Mudder socks were developed to integrate Wigwam’s unique design with drirelease® moisture management technology. They excel at keeping feet dry and blister-free during strenuous workouts and demanding athletic challenges,” continues Loferski, “They also look amazing - our product development team has once again delivered a bold design, one that we’re confident the Urban Mudder finisher will be proud to wear.”
