Heel slip - traditional methods are not solving it. Need boot recs or unconventional methods

I had the same issue. Picked up some Low Tibets from REI and loved the way they felt. Lacing system was great. Perfect.... until I hiked a steep hill and my heel started burning.

Switched to Crispis and no heel slip at all. Still a great boot for me, but on flat land I did like the Lowas better due to the lacing system.
