You can get really, really, really thin trainer liner socks.
I used to climb without socks, and it got so I couldn't stand either the stinkyness, and slimey feel of the shoe when I put them on.
So next time I bought new shoes I took some trainer liner socks with me, and made sure the new shoes fitted with them.
Haven't had stinky, slimey shoes since.
