I'm in the process of it all, and will let you know the outcome soonest regarding Poppy Barley (a Canadian company). They make shoes and boots to fit your legs and feet. Can't be bad!
Ted & Muffy is ex-Duo boots and I've had positive feedback from clients. My stylish SIL who lives in London has six pairs of custom-made boots from this company. She has wide feet and calves and they work extremely well for her. She walks her feet off in London each day and needs comfy, durable footwear. They fit the bill.
