The leather is tougher than usual DM footwear. They are designed to be more hardwearing. How that translates into comfort, I don’t know, as the joy of DM’s are that they do change shape to your foot to a greater extent than usual shoes.
Best suggestion is to pop into a DM shop and try them. (Brighton, Covent Garden, ect) You may not like them. Many are not so keen. I’ve seen people in the shop try them and not be smitten.
To be honest, I have 2 pairs, 1 black, 1 brown of ordinary DM’s, and wearing in rotation, I have had over 2 years and they are barely worn on the leather (I do polish them fairly frequently too).
I don’t expect to replace them for at least a year or so longer, and for hygiene reasons are happy to get 3 years + out of daily footwear. I just don’t see the need to spend twice as much, when my present footwear is costing less than £2 pm. I have bigger issues in my life.
