I bought a pair of specialised audax shoes (orange, as they were much cheaper). As i have them i might be in a position to give a brief review. Specialised shoes, both road and mtb types have a wide toe box. I have broad feet and these commodious shoes accomodate my feet and allow for some wiggle room without being sloppy. My right foot frequently develops "hot foot"if i wear other makes of shoe. The fastening combo of velcro straps and dial works very well, with micro adjustment easy on the fly possible. (I was sceptical being old school, however my concerns were unfounded). The point about the three bolt cleat is valid. I prefer spd shoed for time off the bike, its safer. I bought these shoes for long rides>4 hours hoping my right foot wouldnt develop hot foot, so far, after a dozen rides they have proved a sound investment, so the three bolt fixing is for me a price worth paying. For Specialised to call them Audax Shoes is probably a misnomer where the UK audax fraternity is concerned.
I do have Specialised mtb shoes, roomy enough, but theyre a bit clumpy.
