These were very comfortable right from the start. The toe ridge was maybe a teensy bit high but I'm sure I would have gotten used to it, as I've worn Birkenstocks before and always liked them.

I ended up returning them though for one reason....Foot Queefing! As soon as I buckled the straps & put them on, I walked around the house a few times. By the third step, the queefing started. It did not stop. My feet were not sweating in the least, but the foot farts were quite noticeable with every step. My leather Birkenstocks never did that, so I can only assume it is the EVA material these are made of.

I usually don't care much what other people think of me, but one thing I will not subject the public to is foot farting. Sorry, but that is a deal breaker for me. Too bad, because I really liked the comfort and the look.
