How would you affix a heel pad to a shoe? I posted this question on the Shoe care thread, but got nothing. These heel pads that I have on are self sticky, but the sweat/heat made that sticky stuff wear down. Hate having a loose heel pad around when walking. I thought about Shoe Goo, but I don't want to ruin the AE model and logo when/if I sell them. Will Shoe Goo scar the leather? Thanks.
