Bull,
First size 15 I ever saw. Used to wear a B width, but now EE.
If Mittzy found long lasting clutches and rear tires, he could contribute to the Bootless Orphans, with all the savings.
Big feet do not propel all that well. Used to use Scubapro jet fins, and thought they "rocketed" me along just fine. I actually got forty some odd on one tank a couple weeks ago. But the rumble off the exhaust is worth the cost of twisting the throttle.
Maybe if I just wear slippers and drag my toes on the tarmac, I can get down to a size ten.
