Security 
Synthetic overlays on the New Balance MT 110v2 are much more substantial than its predecessor, which improves security from heel to midfoot. A classic lace system wraps the overlays securely throughout the midfoot. Moderate heel padding and a secure ankle collar hold the rear foot in place effectively.

Stability
Outsole lugging is more aggressive than the original MT110; the lugs are deep enough to grip loose dirt and wide enough to shed mud easily. The Vibram rubber compound provided steady grip in wet and dry conditions with solid footholds in all of my test conditions. A low profile and almost-flat platform further improved stability on technical terrain.

Smoothness
New Balance switched the midsole material in the MT 110v2 from Acteva Lite EVA to RevLite, giving the platform a softer feel and good responsiveness from heel to toe. The forefoot flexibility was fair, with a more rigid rearfoot area.

Comfort
I found the biggest downside of the increased synthetic overlays in the upper was a noticeable decline in breathability and drying time. That also caused the MT 110v2 to run hot in high temperatures. The toe box area created some hot spots on the lateral toes during multi-hour outings. The sockliner and interior padding are all comfortable against the foot.

Speed and agility
With a full rockplate and outstanding traction, it was easy to bomb down hills and rip through rough terrain. However, the New Balance MT 110v2 is noticeably heavier than its predecessor, and the additional weight will potentially slow you down in the long run.
