Strengths: Perfect,straight from the box to racing. The 901 fell short from the 900 but the major changes have put this range back in competition with others.
Weaknesses: The only,and for me, the biggest weakness is that I have to buy my 902s from the USA as NB don't do a 2E fitting in the UK!!!
Overall: This shoe is not only for the racing snakes but heavier runners as well(I'm 14.5 stone)and have used them for ultra distances. The cushioning is far superior to the 901 without compromising on the weight. Overall a fantastic performance shoe for the heavier runner
