Nothing better for wet days, or wet pavement. Size L fits 44.5 Sidi Genius. If it's wet outside there is no point trying to stay dry because eventually you can't so why not go with the "warm wet" you get with neoprene? Neoprene covers fit snug, without wrinkles. The cleat holes line up fine with Look/Shimano sole. If they were about 2cm taller I'd give 'em five stars.
