I wear a 44. Size guide suggests XL/XXL. I purchased M/L and XL/XXL to be safe. I ended up returning the XL/XXL as they were considerably bigger and oversized. Definitely not for a size 44 shoe. Besides that, the quality and design are awesome! :)

These are great but if your bibs get wet around the shin area, they’ll let water through inside. Better to wear bibs that don’t go under the shoe covers or pull the bibs over the shoe cover.

Great fit but so tight over both size shoes (50s are for using USB heaters & extra socks on proper Tassie winter days), I put these on first before my shoes, then adjust down. I'm not going to try getting these over my shoes, ever. These run around 18cm above my ankle bones. As yet untested in proper wet or winter conditions.

Kinda easy to get on. Kinda hard to get off. First ride today and discovered that they were totally drenched on the inside from sweat. They definitively don’t breathe. Definitely kept my feet warm though. Temperature was about 40° so they will probably keep my feet warm in much colder temperatures.

I have tried so many different shoe covers each year. I commute about 30 miles a day by bike and ride on the weekends as well. I go through about three pairs every year cause they either are lacking in some area and I cannot bother to wear them again, or they are so poor in quality I just toss them. I purchased these just before the weather turned this year in Chicago. They have been a life-saver. Heavy rain, sleet, and some snow and these performed amazing! Combo with some deep winter socks and they will keep you warm for those long winter sessions. I have also tried them with summer socks on days in mid-high 30s (farenheit) and are still warm, but not so much that you find yourself sweating 10 minutes into your ride. Must have and I am definitely picking up the tall version for January/February.
