I am a long time Brooks Adrenlaine shoe person but unfortunately they have changed the 15 so I will have to look elsewhere.  I walk 3-4 miles everyday and am on my feet a lot.  I buy Brooks Adrenaline for the wide toe box and I buy a whole size larger than my normal shoe size.  So I was very surprised when after wearing these just once, my toes on the left foot rubbed together and gave me blisters.  I have tired different inserts to see if it would help but have given up.  So I just wasted $120 on these shoes - very disappointed.
