Over the past year, we have been tirelessly developing the design of this binding with the following objectives in mind: 1. Design the world's comfiest binding, for use with socks, barefoot or with regular shoes; 2. No sharp edges; 3. Use only high-quality materials and make the bindings ultra durable; and 4. One size fits all. After achieving these 4 objectives, we are finally ready to say that we have done it! We are stoked to bring you the world's comfiest, most durable training board binding around, with no sharp edges and the ability to fit almost anyone and any age!
