Current shoe mileage: 176
Intro: The Nike Kiger 6 has become a trusted favorite in my quiver of running shoes. Though it's not perfect, it's reliable. It fits my feet well, is fairly light, but still durable and comfortable for regular training miles.
Outsole: Honestly I hate to start with the outsole because when I hear complaints about the Kiger, it's usually with the outsole. I've heard people describe it as downright "dangerous" in the wet. While I acknowledge that it's not great in the wet, I haven't really had any problems with it either. I just know it's not going to grab super well in wet conditions, but it doesn't really bother me. Granted because of this it wouldn't be my pick for a short fast race in the rain, but for training I've found it to be fine. Not great, but not the end of the world. And yes, I do find this aspect of the Kiger very ironic as Nike is based in Portland OR, one of the wettest cities in the US!
The other issue I've seen with the outsole is premature wear. Now I would say long term, the outsole holds up great, but initially the lugs wear quite fast -- disturbingly so. But as they wear down, the lug itself gets bigger as the base of each lug is much wider than the top. So after some quick initial wear, it slows considerably and the outsole lasts for quite awhile.
Midsole: The midsole of the Nike Kiger 6 is Nike's famous React foam with a Zoom Air unit in the heel. Nike's React midsole is loved far and wide by many many people and I understand why. Somehow it strikes a wonderful balance of being soft and comfortable while also being responsive. The Kiger has just enough of this midsole to protect your feet for decently long runs, but it also feels nimble enough to tackle technical terrain.
Upper: The upper of the Kiger is light and flexible, but it wraps your mid-foot well enough to comfortably lock down your foot. The toe-box is a little shallow, but it has enough room that I haven't had any problems with rubbing. This is one of the big reasons I love the Kiger 6 -- it can hold my foot securely in place without needlessly constricting it either. The laces are okay, but could be better. I find that I have do make sure I pull that double-knot super tight to keep them from coming untied during a run. I also think if they were a bit wider (maybe like the Brooks Catamount), they would be even more comfortable when locking down that midfoot for steep downhills.
Durability: Despite the initial wear on the outsole noted above, the Nike Air Zoom Terra Kiger 6 holds up quite well. I don't see any issue getting this shoe to 300 miles.
