I read mixed reviews about these shoes when I bought them, one of them being a somewhat negative review indicating something of a odd feeling under the foot near the heel. When I got these shoes and started running in them I also felt something odd but did not think much of it, thinking it is just the shoe and since it did not immediately feel uncomfortable I decided to keep at it. I like the appearance of the shoe and ASICS are supposed to be a good running shoe, so I wanted to give it a chance. After running in them about 4-5 times a week for a few months as well as doing some uphill sprints, I began developing some kind of foot pain around the heal area which until now (over a year later) I feel like I am still recovering from. Discomfort under the heel could be felt, but the big problem was at the Achilles insertion point. A few people suggested to try new shoes, I should have listened earlier. I feel like there is something not right with this shoe, just as others have pointed out in other reviews. I don't think there is enough support around the heal area, and the foot bed or sole of the shoe under the heal is odd. Maybe its me, and a few others who experienced the same, I don't know.
