This shoe takes over from the GTS 6 which used the fantastic S257 EVA midsole, the introduction of Brooks MoGo midsole, which is a polymer, is an incredible improvement. For those who do not understand the polymer midsole it very simply creates a soft midsole which is more responsive and will outlast any conventional EVA midsole due to he fact that polymers are not nearly as likely to bottom out meaning the shoe will go on and on way past the 500 mile mark. The control is amazing, I used to use an Asics creed followed by the Empire and the Empire 2, all specific to late phase pronation, but this little beauty has allowed me to use the full natural motion of the foot and my running is going from strength to strength. The upper suits a narrow heel and wide forefoot which is the typical european/Brit foot shape and allows the foot to do what it naturally wants to do with enough control to prevent agravating the connecting joints. I have now seen roughly 40 members of our club using this and they would all agree its probably the best shoe on the market for the mild to moderate overpronator provided the fit works for you.
Brooks....Keep up the good work and lets not make too many changes to this fantastic product.
