While we have been using Solestar custom orthosis for all cycling shoes for the past three years we have now introduced a Mountain Bike specific range of orthotics that offer the control of a custom orthotic with the cushion that is required for mountain biking. We stock a full range of sizes. Check out www.solestar.com for more information. When attending for a fitting of cylcing specific orthotics we ask you to bring along your cylcing shoes so can assess your cleet position and make any adjustments required. Philip Spark
