I also gained a full shoe size but never got any benefits. I was so pissed off at Innov8, telling their customer service their QA sucked. Then I measured my feet. Whoops.. but wtf? Carpal tunnel, permanent cramping in wrists from what I assume is overgrowth of soft tissue. I'm even an inch taller somehow. Don't know how that happened. Anyway, acromegaly isn't good. What kind of tradeoff is good enough to accept it unless it was your dick? I never got any sleep, fat loss, any kind of positive benefit. My body didn't know what to do with it, clearly. "Wtf is this?" "Just make his feet grow bigger and throw the rest in his wrists."
