Women's Over-The-Knee Stretch Flat Block-Heel Boots are your go-to choice for all-day comfort and effortless style. Featuring a slim, close-fitting shaft that reaches mid-thigh, a chunky flat sole, and a flexible stretch back panel, these boots suit a wide range of calf widths and keep you comfortable from morning to evening.

Why You'll Love It

  • Stretch-fit shaft: The elasticated back panel conforms to different calf shapes, giving a sleek, secure fit without discomfort.
  • Easy side zip: A smooth side zip lets you slip the boots on and off quickly, with no fussing over the shaft.
  • Flat chunky sole: The block sole distributes weight evenly for all-day wear without heel fatigue.

Perfect For

Wear them tucked over skinny jeans for casual weekend errands, or style with a knit mini dress for an evening out. They work equally well on city breaks or for smart-casual office days in cooler months.

Care Instructions

  • Wipe clean with a soft, damp cloth.
  • Avoid prolonged exposure to water or direct sunlight.
  • Allow to air-dry fully before storing.
  • Store upright to help the shaft keep its shape.

Frequently Asked Questions

Do the boots accommodate wider calves?
Yes, the elasticated stretch panel at the back is designed to expand and adapt to a range of calf widths for a comfortable, secure fit.

How do you get them on and off?
Each boot features a side zip that allows quick, easy on and off without needing to tug on the shaft.

How high do the boots sit on the leg?
The shaft reaches from the ankle up to mid-thigh, sitting above the knee for an over-the-knee silhouette.
