Sleeping feet

I was just wondering something, i have been using mtb spds on my road bike, and yesterday on my first 100k my feet started going to sleep, and cramping really badly.Would using road spds make a difference as the are bit bigger, its something i don't really know about!
if this is the case, are there any 'touring' based spds people would recommend.just bought new mtb shoes, and don't fancy buying another pair of shoes!

cheers!

sounds like I.D.S. - Imminent Death Syndrome - to me.

only if i was still in london!but this was on a nice hilly 100 in the south of france!

it's probably more to do with cleat position, and/or the fit of the shoe.

maybe move the cleats a bit and don't do the shoes up so tight

ok, cool thanks, i did keep the straps quite loose.it was almost as if i had a 'hot spot' on the ball of my foot!

'tis the shoes, not the cleats methinks

Use superglue!

Oh, sorry. Thought it said slipping feet :(

Put an old penny in your sock before you strap your sidi shoes on.

Could be a number of things. I get a hot right foot with my Sidi's when using Shitmano PD-520 MTB pedals, but not when using the same shoes with a set of classic Dura Ace SPD road pedals. Given up trying to find a medium between the two.

Did I just say that I had Shitmano on my Italian road bike??
