I had the ballet flats (the Primas, they were the original ballet flat!) and they were super comfy. my feet did/do get hot in them, but I just slip them of for a min to let my feet "air out". I do notice though, that no matter how sweaty my feet get in them, they don't get stinky. In my TOMS, they get stinky - and FAST!
I now put Tea Tree Oil on my feet, between my toes, before I go sock-less. It's more natural, and I feel more effective, against stinky feet than spray antiperspirant or foot spray ever was.
I just ordered a pair of the "lavender" style.

They should be delivered today or tomorrow. I can't wait to wear them!
Also, I have a friend who LIVES in the Malindi. She's a teacher and has them in at least 4 colors!
If you have a Crocs outlet near you, try going in there. They have "buy one get one free" or "buy one get one half off" sales a LOT. And it's always nice to try them on since the sizing can be tricky at times with these shoes. If you don't have a crocs outlet near you, try calling random ones to see if they'll ship to you. I find they sometimes have more selection or sizes available than the online store might. Worth a phone call, right? That's how I'm getting my hands on 2 pairs of the discontinued shoes (above.). Called a store in Texas that had them, got one pair half off or free (can't remember but it was only $30 for 2 pairs!), paid for them with a credit card, and got them shipped to me!
