Leather Chelsea Boots - Betty BooThese are our best selling boots revamped to make more contemporary with a lower shaft (15cm), more top of the ankle rather than calf. We've kept and improved all the bests bits and retained the breathable lining, comfortable and anti odor insole. The sole is soooo strong but also lightweight. Welcome to Betty Boo.
