These knee-high boots feature a block heel and come in a neutral tone that works with most wardrobes. The shaft has a lace detail panel down the back that adds visual interest without being too fancy. They zip up the side for easy on and off, and the rounded toe keeps them practical for everyday wear. The block heel gives you a bit of height while staying stable and walkable.
Key Features
- Block Heel: A sturdy, low heel that's easy to walk in and keeps you steady on your feet all day long.

- Side Zip Closure: Makes it simple to slip them on and off while keeping the fit secure around your leg.
- Everyday Versatile: Works with jeans, skirts, dresses, or casual pants for days when you need something that looks put together but feels easy to wear.

The exact composition of this piece is listed in the product description above. To keep natural fibers beautiful:
- Wash wool, cashmere and knitwear by hand or on a gentle cycle at 30°C / 86°F, lay flat to dry.
- Refresh coats and suede by airing them out; use a soft brush for suede.
- Store knitwear folded, never on a hanger, to keep its shape.
