I have plantar fasciitis and find most shoes, not to mention being barefoot,  really painful on my heels.  I sort of stumbled onto Crocs when my husband brought a free pair home to me and even though I find them incredibly ugly, they are AMAZING for my feet.  So I went in search of more and found these Malindi slingbacks.  I bought them in black first, and found them much cuter than the original.  In fact, I think it is hard to tell they are rubber.  They are not as comfortable as the original Crocs but they are better than my regular shoes (including tennis shoes) and I can wear these to work.  I bought them in three colors: navy, black, and berry.  The black honestly fades very quickly, but I do like that when they get dirty I can just throw them in the sink and rinse them off.  The only other quibble is that they do squeak when they are new, so be prepared for some foot farts until they form around your foot a little better.
