Insoles for Crocks

The Ascent "Geelong Urban" shoes I purchased recently came with insoles made of a flexible rubbery plastic covered with fabric on the upper surface. These looked similar to those sole for $70 in shore stores. Unfortunately I had to remove these to put the hard plastic custom made orthotic insoles in the shoes. I was reluctant to throw away the insoles which came with the shoes, but wondered what I could do with them. Then I noticed the material was similar to that of the Crocks moulded plastic sandals. These do not provide good support for flat feet and it is not possible to fit the hard othortics into them. I found that by trimming a little from the toes of the insoles from the shoes, they fitted into the Crocks. This provides better, but still not perfect, arch support.
