i have an insoles and heel pads. the left foot is okay, its loose at the toe from being large but the heel sides are okay, but the right, even with the heel pad and insole, is too loose at the heel. after trying the smaller pair again, it feels fitted but not tight. and there is plenty of toe space even on the smaller pair. in hindsight, i'm not sure why i went with the larger pair. As an update, I messed around with insoles and used a pair from boots, and they made a difference with the heel slipping, which was my biggest problem with them. So I don't need to switch boots anymore. And doc martens still look awesome. What would be better for polishing/sealing them, the dr martens wonder balsam, or sno seal?
