The support ridges in the bottom of the Blue cap can grind into the Gore-Tex boot lining. It is recommended that Superfeet be trimmed so they move 2mm inside the shoe, & this friction eventually makes the ridges slice through the lining. It doesn't happen every time, but it happens often enough for us to make a note in our literature. There is a shoe accessory called a 5-iron that corrects this problem. A 5-iron is a 1/8 inch thick insole-shaped flat sheet of foam/rubber. It comes in two

Sizes: small & large. Superfeet size B-D are small & E-G are large. We do not make the material that 5-irons are made from, but we do cut them from a flat sheet of material. The material comes from a company in Salem, MA & is an EVA Foam & SBR Rubber blend. You should place it between the bottom of the insole & the shoe, & it will keep the ridges from making direct contact with the Gore-Tex.  It is not as common, however any orthotic or Superfeet Premium Insole can have contact with the Gore-Tex lining & create a pressure point on the side or the bottom of the boot which could possibly wear a hole. If you choose to use Superfeet with the Gore-Tex lined boot, inspect your boots often making sure that there is no sand or grit between the orthotic & the bottom of the boot What is the difference between the Blue & the Green? All of the Superfeet products are based on proven biomechanical principles to help create ideal foot function. The differences between the Superfeet models are not in the biomechanical shape. They are in the thickness of the materials used in each of the products. The foam top sheet of the Blue product before it is molded into shape is 1/4 thick. The Green foam thickness is 3/8 thick. This makes the Green product 1/8 inch thicker than the Blue. Because the Blue product is produced from a thinner sheet of foam, there is less foam volume in the arch area on the product. As a result of this some flat feet may feel the Blue product is more comfortable than the Green. The Green product is thicker in volume, therefore it will fit into shoes that offer more room. The Blue product is thinner in volume, therefore it will fit into shoes with less room.STILL NOT SURE? CLICK HERE FOR MORE INFORMATION
