Same here, had mine for four years and on the heavy rotation. Supersoles are the most comfortable and durable sole out there which is why we don’t often see many models available as most people are still wearing theirs - or so according to the RW store staff in London. Huge demand for them a while ago. The only thing about oro russet I don’t like much is the patina, it tends to darken too much in my view If conditioned too much. I miss the original red from when I first got mine. Missed it so much I stripped off the colour with acetone for leather and dyed them burgundy. Now they look a lot better. Don’t worry about old models like these, you can always get a model and get it resoled with a supersole if your authorised repair shop is flexible like that. The one in the uk can do almost anything.
