The insole is a premium sheepskin leather with a memory-foam cushion underneath. The knit ��sock�� insert adds style and comfort. The opening on the side lends visual interest and also makes it easy to put on and remove. The white sole has a dark navy layer on the bottom, which makes it a little easier to keep clean. The upper is 100% real leather, and is hand-stitched to the sole with a leather welt. These are a medium width shoe, but will stretch slightly to accommodate a?wider footbed as well. If you need a half-size, consider buying the next size up.??
