I've checked PBK and they don't carry half sizes, also I have seen cheaper online. I know you have to keep an eye on PBK because they have killer deals (I'm waiting on some Keo Carbons from them) I'm currently in a 43.5 Sidi Energy that fits just right, if not a bit snug. I know a 44 would be too big and a 43 too small. Hence the reason for looking for a shop so I can confirm if the shoe works or not.
