My second pair of Siberian Booties and they are great at keeping my feet warm and dry on those winter sorties.
All my Craft garments are essential to my rides whether summer or winter.
Bought an XL rated for up to size 48. Tore off the heel pulling trying to pull bootie onto a size 47 road shoe. I was never able to stretch the bootie over my shoe because of the enclosed heel. Bought comparable Pearl Izumi and they fit great.
Seriously undersized. Order a size larger. (In my struggles to get it over the shoe, I broke off one of the pull tabs.) Also, contrary to the description, it DOES have zippers!
The pluses: very warm, and I think they made an effort to create a quality product. I might recommend this product, but would insist on ordering a size up.
