Based on sample of N=1 I'd say Specialized come up a little smaller than Northwave, but that's comparing a Specialized tri shoe to a Northwave winter MTB boot so possibly not the best comparison.

Best advice is try it on or at least order from somewhere you can return for a full refund if it doesn't fit. Life is too short for uncomfortable bike shoes!

Thanks, that’s why I’m asking. The only vendor is from another country so I would have to pay the shipping back if it doesn’t fit, probably worth the try.

I own the Sepcialized Road expert and Northwave Extreme RR, both in EU size 48, and my feeling is the Northwave is half a size smaller.

Very helpful thanx a lot.

I have Special S-works and Northwave Extreme. Both have 2 BOAs and no velcro straps. I wear a US12 for dress shoes and a 13 for running shoes. 47 in Specialized and 46 in Northwave. Both fit well.

Ok, now we have some seems a little smaller,others same and others a little bigger ;-)
I’ll give the same size a try and let ya all know when I get em.
