The heel is not the point. A flat knee high boot does everything a heeled one does in terms of polish and intention, and then it lets you actually get on with your day. That is the argument for them and it is a good one. We have been pulling together the flat knee high boots that genuinely earn their place, the ones in leather that moulds with wear, the ones with a sole substantial enough to handle real pavements, the ones that look just as considered with a midi skirt as they do tucked into straight leg jeans. The fit around the calf matters more than people realise. Too loose and the whole thing looks sloppy. Too structured and you spend the day thinking about your legs. The best ones sit somewhere in between, holding their shape without gripping. We have favourites in both sleek and more relaxed silhouettes because the occasion dictates which you reach for. These are the boots that live by the door rather than at the back of the wardrobe, worn constantly, replaced reluctantly when they finally give out.
