Strengths: I've had Male 3D Grid Triumph versions 1, 2 and now 3 the Cushioning throughout makes them very smooth.
Weaknesses: Could be more flexible but being a supinator it seems no supplier really caters for us. Remember to break them in parallel with phasing out your old pair.
Overall: Surf the web and the 80 pound rrp can be dropped to 60, for a top of the range shoe this is very good value for money.
