I have a pair that I bought for my husband when he felt inspired to learn to ride. Unfortunately he did not continue. I think they are a size 8 or 9 and are somewhere in the cupboard upstairs. If they are the right size and would like a picture let me know
My husband bought some Shires Norfolk Long leather zip up boots and is very pleased with them. About £100 and decent leather. He is blessed with a powerful but not tall and willowy physique (typical Yorkshireman ;-) ) so had to have the tops shortened but this was easy to do through a good cobbler, a decent saddler would also likely do this. Good luck finding some
Ariat Bromant (I think thats what they are called) lasted me 3 years which is good going but for a price tag of £300+ I decided to get some Brogini's and they have been great I love the leather and the fit gives a real close contact feel to the horse.
