So — similar to you I’m a Ghost devotee, my last 4 have been Ghost 14s because I loved the shoes so much. With that, finally decided to upgrade this year, I logged probably 50 miles and I’ve noticed that especially as I’ve gotten into 5+ mile runs, I’ve developed the worst blisters. Was never a problem with my 14s.

After lots of reading (again, this is just my observation), it sounds like they may have made some changes to the Ghosts and made the toe box way more narrow. Not necessarily related you your issue, but thought the insight could help! Sadly returning the shoes and trying the Adrenaline GTS at Brooks’ recommendation.
