I think I've experienced what many have in terms of the &#34;spines&#34; or &#34;blades&#34; coming undone from the sole. I work in an operating room and love the feel of these shoes. I've been at work 2 days sonce I bought them and already, having malfunctions. Super glue? We will see. Not thrilled. I realize the seller has nothing to do with this. Adidas should repair or refund.
