In this Instructable, I'll be sharing with you the repairs I did to bring my Patagonia Huckleberry shoes back up to snuff. The heel lining was worn through in one of the shoes, so I'll walk you through replacing the other lining.
These repairs took a couple of scraps of cloth, a little bit of thread, and couple of hours of work.
Step 1: Remove the Old Lining
Use a seam ripper or razor blade to tear out the old seam and remove the lining fabric. It will likely be attached with some sort of spray adhesive to several layers of foam. You will need to pry up the sub-footbed of the shoe (correct term?) and pull the tail of the fabric from the bottom of the shoe.
