These are light and very comfortable.  Size runs true, but these are not the wide box shoes that the Torrin 2.0 was. They do have a wider toe box then most other shoes I have used. I tried these because I am disappointed in the evolution of the Altra Torrin product. (Toe-box is now too small) These have a thicker sole and will take some getting use to.  I just finished my first five mile run and so far, I am happy with them.  I need to run in them awhile to know for sure if I have found my replacement shoe.  I run 20-25 miles a week and I am a heavy man (280 lbs). I use up running shoes quickly. Longevity is not an Altra strong suit but I am willing to buy more shoes if I can wear a perfect fit like the Torrin 2.0.
