what fun I've spent the last 3 hours trying to install these things! My boots were not worn through the old ones , but were getting close. getting them off wasn't too bad. followed directions for glue and had no luck. they were spooned up from packaging. and wouldn't lay flat on the boot sole. the glue wouldn't hold them. finally i broke out the staple gun with 1/2 inch staples ,and caked them with the glue again and stapled them onto the sole. they are too wide so i will have to trim them. hope the glue holds when i take out the staples next week. Thank goodness I have another pair of boots!
