I have been loyal to Hoka pretty much since I started my running adventure, but I have had to return my last 2 purchases as they just don't feel right anymore. The sizing has changed (a lot) and they were uncomfortable around the ankle. As I had knee issues prior to getting Hokas I am apprehensive about the switch, but my remaining pair has not got much life left in them. Some googling tells me that Brooks Adrenaline GTS is comparable, and they are on sale...
I have got them. The insoles are the same size as my Hokas. The base has a similarly configured tread/support pattern. They feel really comfortable, maybe slightly roomier, I'm not certain, so it can't be that different.
All that's left is a road test, so I'll do a 3km test tomorrow
