Edwardian boots were fashionable from 1900 to 1910. These boots were typically made of leather or satin, with a high shaft that reached mid-calf, fastened either with buttons or laces all the way up. They were often brown or black, with pointed toes. The heel could be a classic curved "French heel" or a broader block heel. At the end of the century, Mary Jane shoes and Oxford shoes started to become popular as well.

Women’s fashion in the 1910s focused on the S-curve, created by a corset that pushed the chest forward and created a wasp waist. Dresses were ankle-length and had a long, slim line. Over the decade, waistlines rose, dresses became more draped, and corsets loosened. Dress lengths shortened and became more practical.Source: Tidens Mode by Anne-Grete Steckhahn

There is no strict definition of when something is considered vintage, but it generally refers to clothing and accessories from 1920-1960. Anything from before 1920 is usually classified as antique.

The Victorian era usually covers the reign of the British Queen Victoria from 1837 to 1901, whereas the Edwardian era takes name after her son King Edward III who reigned from 1901 to 1910. The era usually stretches to 1914, with the beginning of WW1. 

Victorian fashion is characterized by huge crinolines and decorated dresses, whereas Edwardian fashion typically is more slim and simple.
