I'm on the hunt for a pair of brown cowboy boots (knee length or mid ankle), but keen to find a brand that's comfy and easy on my back and feet. I can't wear heels due to a bad back/knees and usually prefer Josef Seibel and Reiker (who specialise in shock-proof shoes), but I've had a look online and they aren't selling any... I'm looking for a second-hand pair - can anyone recommend any good brands to search for?
