severe lack of shoes: part deux

right to left: Brando nappa leather over the knee boots; CL-wannabe "ariella" studded boots, vintage leather and stud flat boots, wittner oxfords, juicy couture ring flats

my more worn in shoes, the brandos are the most expensive shoes i ever bought coming in first at 499$, they are probably the best quality leather Ive ever seen, the perfect tall flat riding boot. the cl wannabes were cheap as chips at about 90$, as compared to the real thing, they're leather and are so comfy for the height, next we have the brown flat boots, they are so old and beaten up from work and festivals and stuff that i cant even read the label anymore, wittner oxfords were my favourite last year but i haven't worn them this year at all. I'm thinking of going over the white thread with a permanent marker cause it bothers me for some reason. juicy couture flats back from the day, simple, soft and comfy, thin lambskin which doesn't kill my feet in the hot summer. and that's it.. i am really in need for some shoes, Ive been saving up for classic chanel flats but every time i have enough money my fav colour and style are out of stock, someone recommend i try ebay but im so scared that they wont fit, I'm always scared of buying shoes online, but its even harder with flats because once they re too big or too small there are no buckles or zips to adjust them. anybody have any tips of buying flat ballerina type shoes online? my feet are between 37.5 and 38.
