In reply to Cooper: Cooper, if it helps, I take a size 47 in Scarpa Manta & have xl yeti's, even though it takes a bit of a struggle to fit them, they still fit my 48 Scarpa Sl's too. I therefore suggest a 'large'would do you as the tighter rand fitting the better.....even though it is going to be a bit of a wrestle to get them on!
