Since I have not actually sat in them I can not give you a definitive answer on that except to say that walking by them they do not appear to be constrained by anything. You can just throw out Seat Gurus assessments though. They have obviously never been on the plane and are just making assumptions in their assessment of EVA's 777-300's economy seating. For example they state 45A,K and 60A,K are partially blocked by the emergency slides and you must angle your legs to stretch out. This is false. Those seats are not obstructed by the emergency slides. They state 57A,K and 69-71A,K have extra room on window side. This is false. The "missing seats" are on the aisle side and the seats are lined up normally against the side of the plane. I wouldn't trust Seat Guru to much on this one.
