Boots for beginning track rider

My dualsport boots Gaerne Balance run pretty wide. I don't know if it's the same for their track boots, but yeah best bet go try them on so you get the correct size.

I almost had to wear a pair of TCX boots for the CSC endurance race last month, as my Sidi's were nowhere to be found for a short while. Not sure what model they were, but all I know is I didnt like them. The felt like they were just large, (not too big size wise, but the shell of the boot was just physically big.) and they felt like they were very flexible around the ankle to me. Never did ride them though as I ended up finding my Sidi's, but that was enough to tell me I sure am glad I wear Sidi's.

The TCX also felt like it was cut for a wider foot.

How's Sidi sizing as compared to A-stars? I'm a 43 Euro - I've had Diadora and I've been very happy with them. Crashed in them and it saves my ankles, feet many times.
