This may be the stupidest question ever. But, what the heck. I've been riding on the same Axo spd shoes for over a decade. After my last adventure race I just couldn't get the smell of Florida swamp out of the ol' dogs so I figured it was time for some new. The shoes arrived from Performance Bike, they fit nice, feel good. Pat myself on the back for saving a few greenbacks. Only thing is, I just can't, for the life of me, figure out what the aluminum spikes are supposed to be for. I understand 'em on golf shoes and football cleats. Why in h-e-double-toothpicks would I need spikes on my bike shoes?

Try and suppress your giggling until I can understand, please.
