Cascadia 16 is a good upgrade from the previous versions I had 11, 12 and 13 in my opinion. My last pair of 13s lasted a long time. The best improvement is the stone protection plate in the outsole. It is invisible when walking and running on flat surfaces, on rocky and rooted places it makes my feet happy. They fit just like the previous generation Cascadia. The new material around the toe box feels strong and probably has good wear resistance.
