I have made a few pair of shoes over the years.

go to your local cobbler, failing one, go to a shoe repair place, ASK them for enough glue to do the job. buy a new sole from them, clean both surfaces, apply glue, when tacky, stick the new soles to the boots, apply pressure, wait, and you are done with the glue is set and dry.


If you really want to canabilze the running shoes, go for it! If they do not match in size you will be fine if they are wider/longer.. you can whittle them down with a good sharp knife...
