I'm over 400# and love my Crocs - I took a walk w/the wife the other day around the neighborhood, a mile and a half trek (a good ways for me) and my feet were A-OK (why she picked nearly the hottest part of the afternoon to go, I'll never know)
I love sandals/flip-flops/Crocs when around the house, just a trip to the store, etc (or barefeet, really) but the Crocs are not really providing much protection from fire ants (I'm bank-bound) - last two times the little boogers have eat me up, one time pretty bad
For sneakers (teenee shoes), I have totally fallen in love w/New Balance running shoes. I used to always get the cross-trainers in the $40-60 range. I tried a pair of 992s ($100+ running shoes) and never looked back - HUGE difference when I have to be on my feet for a large part of the day. The model # now is 993.
I kept balking at getting some high-dollar running shoes b/c of a pair of Nikes I had forever ago. Nikes are not made wide OR for people my size. NB offers many styles/designs in wider sizes (I wear a 15 EW = Extra Wide = EEEE) & last a long time, IMO. I now know my size & can order online with 100% confidence.
Next time you are at the mall, duck into one of the shoes stores & ask 'em what they have in 15s. If they don't laugh, they will go to the back & in 20 min return w/two giant boxes. One will be a pair of white, hi-top b-ball shoes. The other box is the black pair.
