yes.
i wear an 11.5, make an effort to find shoes that let me get my foot deep in the clip (sambas) and I find a M christophe clip pretty ok. I compared the M christophe to the MKS and they are about the same size.
i put a LL mks clip on my bike and those were too big by a large margin. crazy toe overlap as well as feeling way too big. I'm gonna order a L mks clip next time i order some **** from somewhere.
