Asics has been trying to make the motion-control more natural on some of its shoes over the last couple of years by slowing and guiding the foot, rather than just restricting it with firm medial posts. Now its the turn of the Gel Koji GS, which replaces the venerable MC+
at the top of its motion-control range.
First signs are that its a better shoe in almost every way. Its certainly more wearable. The midsole has been scooped out in the midfoot for a smoother ride, and theres a very slight curve in the last of the shoe, for increased smoothness. Normally these things would compromise stability, but Asics has added enough new control features to hopefully balance this out. Starting at the back of the shoe, Asics has built in a heavy-duty version of its Impact Guidance System, and the section of it that cradles the foot extends further forward on both sides than the more basic version on the MC+ did. The Koji also
features two plastic fins in the midsole, and the laces pull the side straps of the logo snug, to give more support than the MC+ did. From a wearability angle, the midsole is rounded to the shape of the foot rather than being flat, and the heelstrike is smoother and more natural.
We didnt have big enough weartest
samples to get reports from our heavier testers and most severe overpronators, so we cant tell you whether Koji matches the MC+
for the most extreme runners, but it
The Koji is the smoother replacement to Asicss top-end MC+. Its not lighter, but its more
wearable in almost every way.
