I'm in the market for some knee high boots. Mine are 25 years old from m&s. I have £500 and ideally would like two pairs one black and one brown. I'm 55 so they will probably be the last pair I buy. I work from home, rarely go out so they need to be fairly flat, easy to drive in. I have ankle boots, biker boots and wellies. These are specifically to wear with jumper dresses at networking events. I'm a size 4.5 and that's important as a 5 slips around and causes blisters. M&s generally have half sizes but do any fancier shops have them? Clueless of Brighton
