Mine do not make a noise!!! They did once but that was after paddling in the sea but as soon as they dried it stopped. Worn them several times and not had a problem, one of us must have strange feet! Maybe you should ask Jaynie as she has a pair too now!! I love mine so all is well in Kay land!!! My least favourite out of all my crocs are the primas cos they ain't that comfy, wouldn't like to walk too far in them! Strictly car to bar shoes and nothing else!!
Only asking as there was a pair of US6 in black/white on eBay, quite cheap at mo, but ages to go on bidding! Says it's suitable for UK3/4 so was just checking!
