Last weekend I went Mountain biking. I don't mountain bike a lot, but it was a crisp, clear (read as cold) morning promising frozen mud, so I figured, "Hey why not?" I had some gear to review and this was the best shot at getting it done, so I suited up including my Pearl Izumi Amphib Shoe Covers. Now this was a dead give away to all the mud hogs that I was really a roadie, but hey, what'd I care. I mean my feet stayed dry and warm. When I got off the bike and had the last laugh, I walked normally since I could still feel my toes and since they still worked. Other riders I was with, who were not so equipped, blamed their funny gait on the shoes they were wearing. I blame it on the Booties that they were not!
Featuring velcro ankle closures and zippered sides, you simply stick your shoed foot into the toe of these booties, push the toe home, zip up the inseam and flap over the velcro, and you are pretty much ready to go. With cutouts for your cleats and heels, these booties are designed for riding as well as walking and aside from noticing that I have significantly warmer feet, frankly I forget that I am wearing them.
The only issue I have discovered with the booties (shoe covers) is that when I attempt to use them with combined platform/clipless spd's the thickness of the material which surrounds the clip hole is too great to allow the cleat to seat in the pedal, but with regular clipless pedals the covers work just fine.
The covers are aerodynamically slippery. They don't contribute much weight, don't get in your way, and don't hamper your performance in any way that this reviewer noticed. However, they do keep your feet a whole lot warmer and in my case that makes each and every winter ride a whole lot more pleasurable.
