I was surprised by these sandals. Crocs are the only brand of shoes I wear every day; I have many styles including a couple of the flip flops, so I was eager to try this new version. However, these ABF singles are not at all like the others: They're quite stiff and feel like a harder plastic than the other types of Crocs. They also run about a size too small and are built for narrow feet: I had to return my first pair and re-order the next size up. It didn't help much. The toe post is much too thick and hard, and it really rubs: I even tried to stretch out the toe post by pulling with my hands to see if I could make it a little narrower, but it is still uncomfortable and leaves red welts between my toes. I've been wearing mine for an hour or so a day for the last 2 weeks but they're not breaking in well. I'm really disappointed because I truly love Crocs as a brand. If you're looking for a really scrumptious, comfy flip flop definitely go for the Crocs Modi which are worth every penny. The ABFs are a dud.
