I wanted to love these boots - I have the same type but from the previous season (that I love!), but they were insulated (which maybe made them tighter around the ankles). My heel moves too far up and down in these; it doesn't seem like they are tight enough around the ankle. This is the third pair of Keen slip on boots that I have had this issue with this season. Unfortunately I am going to have to find another brand of boots that fits better around the ankles.
