I'm about to purchase a pair of Northwave Celsius GTX MTB Cycling Boots and have a few sizing questions. I hear these run small. I wear a men's 10 regular width. I think that's a 43. If they run small, I would go to a 44 and if I want to leave some room for the toes to wiggle and occasionally thicker socks, I would go to a 45. Is this correct? I was going to order from bike bling, but they are out of 45's. If I order from a UK company, I will not be able to easily make a return, so I need to make sure this goes down right the 1st time.
If you think that they will run small I would order 3 sizes large. Since normally in winter you want them to be 2 sizes over if you are going to be riding in below freezing temperatures. If you are going to be riding only down to 40 F degrees or so, then 1 size over is probably Ok.
