I recently returned from the 2016 Winter Market, the ORShow in Salt Lake City. While there I got the opportunity to check out and test a pair of the ICEBUG Slim/Medium Insoles with Arch Flex System Technology. Check them out on AMAZON. Running shoe insoles with energy return zones improvement over stock insoles.
Icebug is well known for their winter footwear and trail running and orienteering shoes. It was a real pleasure to check out their products for the coming year at the Outdoor Retailer show. If you enjoy winter footwear as much as I do, check out the following suggestions.
