If I were you, I wouldn't risk buying something online without it fitting, but if you feel comfortable enough to do so, then go for it. You may get lucky and get a perfect fit
I'm not happy with this situation , but its impossible to buy for example salomon boots in my country. Our snowboard market is so poor , its hard to find something else than ride , burton or dc(2 years old models for full price
). So i have to risk and try it this way, hope they will fit.
