Am looking for a pair of knee length flat boots to wear with everything, budget around £50. I have large feet (UK size 8, european 41-42, depending on width). Has anybody seen anything like this that might fit the bill? I'd love to go and have a wander in town for them but with 4 year old and 6 month old there doesn't seem to be much opportunity. The budget probably restricts things a bit as well. All suggestions gratefully received.
