Great Winter Bootie!
I wear Euro 46/US 11.5 Sidi shoes and the XXL booties fit perfectly! They are very sturdy/durable and I can already tell they are going to be warm and last for many seasons. They have a zipper in the back and a velcro closure to cover up the zipper. I typically do not ride if it's below 40, but these will do the trick to suit my needs. Highly recommended for a winter bootie that's lightweight and not bulky, while still providing great warmth and wind protection.
