I would recommend a 1/2 to full size larger. I also happen to have a wide foot and these ARE comfy! Simply put, the best trail runner I have owned thus far and I immediately ordered another pair. This is coming from an avid, daily runner putting in 30-40 miles per week both on, and off road. I have had deals with: Hoka One One, Newton, Altra, Topo Athletics and Asics. I switched to the boost the year they debuted (2012 I think) and really loved the energy return and the shoe in general. However, they were too narrow at that time, so I have run a number of other shoe brands/types between then and now waiting for Adidas to figure it out. Since then, Adidas has made the shoe a lot more roomy in the toebox. Tons of cush and great energy return. Ample protection off road and solid grip. Very confident on all surface types and conditions in this shoe. These are absolutely the best for trail running, daily wear, hiking, camping etc. I even run them on road some days. Hope this helped!
