I have been putting off purchasing cycling shoes for some time now, but I finally decided to pick these up because they went on sale!  I read as many reviews as I could to determine what size I needed due to the fact that these shoes ran between 1/2 size small to a full size.  I wear a Nike 9.5 and went with the majority of people who said to go up at least 1/2 size so I went ahead and ordered the size 44EU.  I guess I got lucky because the shoe fits perfectly, with plenty of room in the toe box.  I used them in my spin class the day I got them and I didn't have any issues with blisters or chafing -- literally no break in period necessary!  The SPD cleats were very easy to install and you may have to remove the inner sole lining because the back plate is taped in place.

As others have said, this is NOT a road cycling shoe but more of a mountain bike; all purpose shoe.  Substantially it has more weight than a road shoe and the sole is probably not as stiff either.  The trade off is there is tread on the sole and the SPD cleat is recessed inside which allows the user to walk around normally without having to take off your shoes or making clanking sounds.  My initial impressions of these shoes are really good.  Fit, construction and materials all seem very good, especially for the $62 price tag.  Can't really beat that!

I will update in a few months after I have a few tri's under my belt with them.
