I love these shoes! I tried on some other brands and was not sure about the fit until I tried these on and realized what a great fit feels like. One thing to know is that the newer models have a thick toe to protect you from bashing rocks which makes them look longer than the true fit is. I measured up on the Sidi foot board at a 43 but ended up returning them for a 43.5 which added just enough room so my toe does not rub when I shoulder and run. A 44 was definitely to big so if you think you need a half size you very well may; my half size was the perfect size. Happy riding!
