These are very comfortable goggles. I can swim for 1.5 hrs and my eye sockets are not crying in pain.
The one drawback - when swimming in a pool, doing a turn (flip or open) the goggle will pull slightly and will cause a leak. The harder you push on the turn, the worse the leak. It''s just the style of goggle, they aren''t sleek and aren''t made for pool sprints. Since I bought these specifically for triathons/open water swimming, I can overlook that flaw. That is the only reason for 4 stars instead of 5. Otherwise, the fit is nice and comfy on the eye sockets.
My normal training pair of goggles are Vanquisher and Vanquisher 2.0
