Hello, thank you for your inquiry. Our Shearling Flat Boots are fully lined in shearling but the foot is crafted of leather.

We do hope this information is helpful.
Kind regards,
Brooks Brothers

Hello, thank you for your inquiry. Our Calfskin, Suede and Shearling Flat Boots do not have a side zipper. The shearling lining has been accounted for in the construction and it does have some "give" to it, so it is not necessary to size up for a proper fit. Of course, you may always return or exchange if these boots do not fit.

We do hope this information is helpful.
Warm regards,
Brooks Brothers

Hello, thank you for your inquiry. Our Calfskin, Suede and Shearling Flat Boots have a standard fit and we recommend ordering your exact size to start. Though there is always a possibility when ordering footwear that the item will not fit, these boots do run true-to-size. The toe box is rounded and more roomy than a pointed, narrow iteration. Additionally, the shearling is intended for warmth and comfort and has much "give" to it.

We do hope this information is helpful.
Kind regards,
Brooks Brothers

Hello, thank you for your inquiry into our Calfskin, Suede and Shearling Flat Boots. For all of our boots, we use the standard calf width, which is about 14”. Please be aware, this boot is shearling lined so the circumference might be slightly smaller.

Kind regards,
Brooks Brothers
