Good, not perfect.
Pretty good for the buck. They wore some blisters when I first went running in them, but then after I walked around in them for a week they seemed to break in and when I went running after that no blisters and they were quite comfortable and provided solid support. I pronate A LOT and they control that very well. They have also lasted a long time compared to most other inserts I've owned.
