A flip flop turned into your own portable gym? Not a bad idea. Trying to make this a trendy gym? Not so cute, but who am I to say considering there is a waiting list thousands long to get these new gladiator Fit Flops from net-a-porter.com. I still can’t get past the lace up front, and at first glance I saw more of a trainer turned flip flop than a gladiator gone wrong.
