i have a pair of leather boots. in one of them, the insole (also leather) is coming out. it's only glued down in the toe and it's all wrinkly. i let them air out (they were all damp and sweaty) and now the insole has dried all funky (all wrinkly and curled up and hard). how can i fix it? if i wipe it with something wet, will it get soft again?
