this is a narrow boot for sure. Wide feet need not apply! Perfect fit for me. Length wise they are almost dead on true to size I take between an 11.5 and a 12 depending on the shoe company and in full tilts I had to go with the 12, so if anything I would say slightly on the smaller side. Right out of the box they were the most comfortable I have ever worn after first day I found the toe box to be a bit roomy for ski boots(I had to go with the 12 due to length of feet) so I heat molded them and they were dead on... If you have narrow feet and want a really comfortable pair of boots I recommend these
