I just tried some of these Giro shoe covers because they were on sale at Nashbar, got the biggest size they offer: Giro Proof Winter Shoe Covers

Tried them on my size 48 SPD MTB shoes that I use for winter commuting: nope. Not even close. I tried them on just my foot with a sock and it BARELY fit even then (I normally wear US 13 shoes). I also tried them on my warmer weather SPD shoes that look more like regular hiker/trainer shoes, not even close on those either.

ughh seems like I can't find anything that fits over these stupid clodhopper shoes/feet that I have. Anyone else wear BIG shoes and have some full shoe covers that work well?
