Strengths: Firm heel box, good control, cool, and they dry very quickly after a soggy run.
Weaknesses: None
Overall: I was a committed wearer of the Omni 5 before I finally moved onto the 6, and I'll be in these for as long as I can get them. I was worried from some of the other reviews about the toe-box fit, but they're like a glove. The new fabric dries faster and keeps the feet cooler than the 5. The Omni 6 is easily the most comfortable stability shoe I've had in years.
