This is the perfect shoe for fast and short races and also speed or interval trainings. Finished 10K Standard Chartered Race in it without any pain and most importantly, the superb ventilation in the shoe allowed my socks to remain dry at all times, preventing any blisters. The shoe is flexible, and allows forefoot or mid-foot strike-off easily. The loop tabs allow fast and easy transition during triathlons. Highly recommend not running in trails or muddy and wet terrains with this shoe as the drainage system might backfire as water can easy seep into the shoe via the holes at the bottom.
The ion-mask technology worked wonders as water and mud didn’t stain the shoe but remained on the surface of the shoe. However, the difference in shoe sizing is one important point to note. Highly advise to try on the shoe before purchasing it. The wide toe box is also another thing to watch out for as even my wide feet had room to wiggle around in the shoe during my runs. The shoe lace material was also another problem as the lace comes loose easily whenever I tied a single knot.
In general, I have only good experiences with this pair of amazingly lightweight shoe, and I would highly recommend it for any runners out there seeking for a good pair of racers.
