Small... but they work

I wear size "42" M077 Shimano MTB shoes and found the Medium Booties a stretch to cover the heels. But after they go over and zipped up, they were fine. No squeeze during pedaling (2-hour rides usually) and did a good job keeping shoes dry in light rain. Not sure how long the stitching will last with the stretching when putting it on. Three rides in, pretty satisfied with the booties, though a Large would have been a better choice for me.
