It would appear that Chelsea boots are having a bit of a moment. The resurgence of ankle boots has prompted love for the classic British style which has previously mainly been associated with men.
A Chelsea boot is defined as "tight-fitting, ankle-high boots of the Victorian era". They were popular in the '60s when The Beatles and The Rolling Stones were often spotted in the style.
Women's Chelsea boots are often heeled. They're tight fitting which makes them easier to walk in. See below for just some of the styles currently available.
