look at the packaging and if you fall in between 2 sizes always go with the one up. you may not try them on if your unsure of which brand fits better get different ones and experment
No
of course not you pick your size and buy them
more specific please
when i first started buying them, I use to try them on to see which size would fit me the best. Once to find the size that fits then there is no need to try them on.
