Well I've just returned from Benidorm ( old town ), were I gave my new crocs a good work-out and apart from getting a couple of blisters, that I remedied this by wearing ankle socks ( whilst remaining stylish ) the shoes were VERY comfortable .
I also realised that I was walking a-bit better, the heels on my old shoes would have been worn down on one side but not my NEW crocs they had a slight loss of heel but it was in the middle of the heel AND on both shoes, this I found to be very reassuring as it took a few days to get use to wearing them.
I noticed that I was walking, as if I had a spring-in-my-step, it was as if the shoes had mini shock absorbers in and I was not dragging my feet along the pavement instead I was walking properly ( heel to toe ) .
WELL, I'M VERY HAPPY WITH MY NEW CROCS AND GIVEN THE TERRAIN THAT OLD BENIDORM HAS ( few hill, not many!!!! ) I THINK THEY HAVE PASSED THE TEST AND HELPED ME TO HAVE A VERY ENJOYABLE TIME WHILST IN BENIBORM and i'm sure they will help me now i'm back in England.
