Review on Pearl IZUMi Barrier Cover Medium by Matt Sirmons

I wear size 43 Sidi mountain bike shoes and have had no problem slipping these Lg sizes over my shoes. The material stretches a bit but the toes don't pinch. The Mt Sidi shoes are well ventilated for hot weather rides, which could mean I'll be cold if the temp drops below 55 during my 2 hour ride. They keep the wind out well and I felt comfortable even in thin socks. I haven't been out in the rain yet, but a little water hose test went well. I have Pearl gloves made from the same material, they are thin, warm and very waterproof.
