Chukkas and Chelsea boots are both ankle boots, but that’s where the similarities stop. Chelsea boots are a versatile, slip-on style boot that features elastic panels on both sides, a pull-tab at the back, and generally a round toe. You can get them in all kinds of materials, but smooth leather is the most common. On the other hand, Chukka boots are a more casual lace-up boot, with two or three eyelets and open lacing. They’re more commonly made with suede, also feature a round toe, and historically, are unlined.
