I've finally got enough disposable income to get a quality pair of boots, and I want to size them right. So, I measured my actual foot, which is 27.62 cm (10.875 in) long and 11.18 cm (4.4 in) wide.
I look through some shoe size charts, which put me between a 10.5 and 11. Cool.
Then, though, I go look at the shoes in my closet and their sizes. Unfortunately, I don't own any boots. Anyway, I wear an 8.5 or 9 in chucks (which I have heard run a size big), and a 9.5 in Vans (which run true?), with approx. 1.25 cm of extra room in the toe in both. Ok, US 9.5-10.
I go to Wikipedia and look up shoe size. The article states that "The inner cavity of a shoe must typically be 15–20 mm longer than the foot, but this relation varies between different types of shoes." So, 1.5-2 cm, about how my Vans fit.
If I go by wikipedia and only leave 15-20 mm of space in the toe, then my shoe size is 9.5. If I go by my foot measurement, it's 11.
Am I just used to wearing my shoes too small? Are boots meant to have nearly an inch of extra space in the toe? What if the boot has a wide toe?
Mostly, I'm frustrated because I've been looking at a pair of boots on sufu, and by one measurement, they should be perfect, while by the other, they are too small. If it's relevant, the shoe has a wide rounded toe, and the upper of the boot is basically flush with the sole. The outersole measurement is 31 cm. Even if I assumed that the material of the boot walls was an entire centimeter thick on toe and heel, that still gives 29 cm on the measurement, room to spare according to Wikipedia. Or am I being dumb, and need schooling on how boots work? Is outsole measurement worth anything at all in trying to size boots?
Help very very much appreciated.
