For the Chelsea Boot Waterproof, we suggest ordering up ½ size larger than your normal US size due to the thickness of the leather and waterproof membrane. The Chelsea Boot has a wide toe box and has a removable insole, so for people who prefer extra depth or better ground feel, you can go ahead and remove the insole. If you have any questions, feel free to contact our customer service team at Lems
