Crocs just came out with a bunch of new styles. I currently have the ones that don't have holes on the top, but there are side vents for ventilation. I believe their new name is the "professional" style. They are six months old, and I work full-time so I need to replace them soon, per the company's recommendation. I can see them wearing down. Maybe you just need a new pair?
I'm ordering the new "relief" style - looks just like the ones I have but are more supportive and orthopedic-like. If you don't mind the holes on the top (though in the OR I'm guessing that's a bad idea) there is a new style called "cloud" that is made for diabetics who have sensitive feet.
I mean, for $39.99, Crocs are one shoe you can experiment with a bit.
