Birkenstock Gizeh

I just bought some Birkenstock-like Aldo, they look like this ...

Ok, so I try them at home and they are an embarrassment "aspiration" noise when I walk! From when my foot moves into the sandal, and when I go out when I walk ...

I do not know what to do! Has anybody ever had this problem? And how can I solve this problem?

OMG! This is too funny I can not imagine the noise. Try putting a little powder on your recovery or the entire foot, wherever the vacuum is created. This could reduce the contact.
