when i bought my Vans Authentics the guy told me to microwave them and then put them on for a more comfortable fit. but he never told me how long to put them in for. (i checked the searchbar, so don't bitch at me for that)
Does this actually help, I've heard of people doing it but never done it myself. My square ones could use a microwave if it will make them softer. The shoelace things aren't that much metal???? try not to blow up though.
That's kinda the point of authentics. You're supposed to wear the fuck out of them and make them the most comfy shoes imaginable.
But I have the same problem, I already sweaty feet and when I go sockless my insoles turn black and have a thin layer of much on them (yes, I know gross) but all you have to do is make a thin paste of baking soda and water and scrub the insoles and they look brand new.
