I have a pair of Le Chameau Extreme wellington boots that I brought in size 10/44.
These are the ones with the insulated soles and much thicker neoprene linings, really snug! These ones....Le Chameau Vierzonord Extreme Wellington Boot | Le Chameau Wellington Boots
However they are a little too big, at first I thought they would be Ok but now I am not sure. I have only worn them a could of times, great condition, no damage or real visible marks.
I am looking for a pair in 9's/43. Not bothered about them being the Extreme ones although great if they are!
Know its a long shot but you don't ask you don't get. I am in Leicester.
