1. Informal testing by doctors in USA indicated a circulation increase about 15% while walking on Step Forward orthotics.
2. Step Flex includes a 5 year warranty against breaking, cracking or splitting with normal use.
3. Step Flex offers a partial refund if unsatisfied, subject to certain conditions. Very few come back.

Why should we mould orthotics to your feet if they are the wrong shape? Much better to change the shape of the feet back to what we know is the correct shape (ie the Step Flex shape).
