Fifty {Two} Shades of Grey - Week 12

Okay so a little bit of catch up here again...

When I bought this item, I didn't spot this particular pattern. It wasn't for a few weeks (maybe even months) that I spotted it. I fell in love instantly because it so reminds me of the pattern on Spiderman's uniform - not sure that makes me a superhero or not... okay probably not!!

So where is it... it is the back of the heel of my Slazenger running (read walking) shoes.
