Interchangeability is a growing trend in the outdoor industry. Makers of sunglasses and snow goggles, such as Switch Vision, have designed interchangeable lenses so only one frame is required regardless of conditions. Now footwear brand Korkers has jumped in with an interchangeable sole for their range of boots. Called the OmniTrax Sole System, the actual outsoles of Korkers boots can be changed out when needed in order to participate in variety of different activities.
