Problem with shoes or with my feet?

[vacaloca]

So I've got a pair of these. I wear them without socks but then they stink. Is that a problem with my feet or this type of shoes? Anything I can do about it? At the moment they're hiding in a cupboard, which is a shame as I really like them and they're very comfy. Anyone know if I can stick them in the washing machine?

I've got a similar pair but haven't noticed they smell partcularly! Can you remove the insoles and rinse those ? Squirt with febreze or bicarb

You could put them in the freezer overnight. This works with trainers as it kills the bacteria that are making the smell!

The insoles don't come out. Interesting about the freezer. I think I'll have to wait until a whole drawer is empty before I dare put my shoes in it!
