The Barefoot Science Foot Strengthening System™ insoles should always present an even, neutral platform for the feet. To ensure that the insoles sit flat in your shoes, please read the following descriptions to determine which version (full or ¾ length) would be most appropriate for your particular needs.

Full length: This version has been designed with extramaterial around the toe area for trimming and is appropriate for shoes that feature a removable insole, such as most athletic and recreational shoes. Typically, the generic insole that comes with these types of shoe is slightly contoured and may interfere with how flat the Barefoot Science System is able to rest in the shoe, so it must be removed. After removing the generic insole, trim the Barefoot Science insole according to the Instructions and place it in the shoe, making sure it lies flat and flush against the ends and sides of the interior of the shoe.

In some cases, the removable insole may be totally flat. You can then choose to replace it with a full length Barefoot Science insole - or - place the 3/4 length Barefoot Science insole over it. In either case, it is vital that the Barefoot Science insole lay flat, that there is as much room in the toe area as possible, and the laces are kept looser than normal.
