i bought the 44 first as the half sizes were very hard to get - then another shop got the 44.5s in and i felt compelled to take them as they say selling the half sizes is very difficult.
i want to keep one pair - and i can fit either pair (i prob prefer the 44.5 b/c i think it gives me more insole and warm sock options, but the 44s have been just fine the last 2 weeks).
the 44s are blue and have been worn since July 25 - i will sell these for $180 + shipping (about $10?)
the 44.5s are black and have not been worn (other than checking the fit - no cleats mounted) - i will sell these for $230 + shipping.
more on fit - shimano boxes say 9.7 and 10.2 for us size conversion - my take is that they fit more like 10.5 and 11.0 compared to my running shoes.
will try to attach pic according to instructions - feel free to message me for email pics/details whatever
