I bought these crocs size 2XL 12/13. I wear size 13 2E and they feel rather tight. My toes are punching out the front holes of these clogs. I had the crocs chinese imitation size 13 and they feel more comfortable than the originals.

Please be warned that these crocs are smaller than the one that came before.

I think I should have bought the crocs baya or clasic as they come in whole sizes rather than a range of sizes. My foot always end up at the larger end of the range.
