Strengths: Neutral cushioning with comfort (roomy toebox) and durablity. Shoes have been great for longer distances of up to 20 miles. Nice, unobtrusive fit. Good wear resistance - 400 miles+ and still going strong
Weaknesses: On the heavy side for lighter runners.Sole struggles for grip on any thing approaching off-road
Overall: Reliable neutral trainers suitable for longer distances
Strengths: Forefoot cushioning and general comfort
Weaknesses: Less room in toebox than previous versions. (Lateral) grip on any off-road surfaces not good
Overall: Comfortable for speedwork or long distance - I found the latest versions a little tight for the toes and cannot unreservedly recommend these for long (13 miles +) runs.
