I use crocs, there cheap, comphy and hold up very well, i had a pair of birkis, they wore out in in under a year, nothing like your shoes craping out on you the week of mothers day. plus the break in period was hell on my feet.
I liked the pair that I had by "Klogs". They lasted me just over a year and a half working 7 days a week 8 months out of the year and a normal 40 hr. 5 day week during the other 4. Just replaced them with a pair of crocs.
I've been wearing the same pair for over 2 years now. I've worn them alot including outside of the kitchen. I've worn sections of the sole down to nothing so that areas are no longer non slip. I'd give them another 6 months probably before they are totally shot, not bad for under 25 bucks.
