I've had my Yukons for about a year. They are the first pair of Crocs brand that I bought, so I chose to try them on (and buy them) locally. I tried a few pairs on and these Yukons seemed to match my feet right from the start.
 I DO understand the complaints about the footbed nubs. They really bugged me for the first few days. After that, either they wore down a little, or my feet just got used to them. Or both.
 I had been looking for shoes that would not leave my feet hurting after a full shift
in a kitchen. I had no luck with other shoes of varying quality and price. Then, I decided to take the advice of a co-worker and tried the Crocs. I'm happy that I took her advice! Rarely do I go home with sore feet. On those particularly hard days when my feet DO hurt, it's not nearly as severe as with other shoes, and my feet seem to rebound faster.
 I highly recommend trying Crocs, and the Yukons in particular. The adjustable heal strap makes them snug without being uncomfortable.
 For what it's worth, Crocs users occasionally snag the little plastic rivets that hold the heal straps on, breaking them. For those of us who use the heal strap around our heals, as opposed to over the top of the fronts of the shoes, a broken rivet leaves our Crocs unwearable. When I first did this, I was devastated. My expensive beloved Crocs were now useless, and another pair of Crocs in another style, that I bought online, were not the answer as they never fit right from day one. (I know, I should have returned them, but you know how it goes) I bit the bullet and wore the other Crocs, but did some research. Perusing the Crocs website taught me that rivet snagging is a common problem. Crocs has a specific area of the site which addresses the problem and will send you new ones free of charge! They sent me about 1/2 dozen new rivet sets very quickly. They're easy to replace. Just insert the back through the hole(s) and snap the front piece on. Easy peasy. I keep a couple of new rivet sets at home, and a couple at work. I have it covered! You might want to get some new rivets right from the start.
Buy The Crocs!
