As you may note from the chart just posted, their sizing is a tad smaller than most metric-sized shoes, at least at the larger end of the scale. I wear a US 11, and in most cycling shoes, a straight-up 45 feels roomy. I relied on their chart and bought my MX-81s in size 45, but found them to be slightly smaller than other brands. Fortunately, they come with fairly thick insoles, and I found that just replacing them with a thinner set gave me a perfect fit.
