Black Leather Knee High Boots A black leather boot is a mainstay all year round, but comes into its own in transitional weather. The Samba boot from Carvela is the last word in stylish versatility, featuring a plush lining which can be revealed when the topline is folded down. A flat heel and a built-up sole offer cushioning comfort underfoot, and an ankle circumference of 295mm delivers a fit that's true to size. Due to the lining, this boot isn't suitable for those needing a wider fit. Finished with a buckled strap and a rounded toe, this boot is ready for any occasion you can think of.
