Comments: I received these shoes a week ago and have done 3 trail runs in them. The shoes are very comfortable and fit great when standing, walking or running on groomed trails. On un-groomed single track etc the lack of forefoot/toe box overlays results in a lot of lateral movement; for me this creates hot spots. I really like the 4mm drop and general feel of the shoe but will wear it only on well groomed trails.

Comments: awesome trail shoe, very nice, snug fit but as others mentioned sizing up 1/2 size is recommended. i run a lot of city trails which means a mix of roads/pavement and single track but not super technical stuff. still unsure if the lack of a rock plate is going to be an issue for me but i love the way these fit from the moment i put them on and i have never been a huge fan of Nike shoes. thought about ordering the TK's for about a month before finally pulling the trigger and very happy that i did. if Nike made a road version of this shoe i have no doubt it would be just as successful as this version. Well done Nike, now don't change a thing!

Comments: Used to Brooks cascadia 7 and Pure Grit2, I had to size up 1/2 number for Terra Kiger. 47 y.o. 80 kg I use them for 10k trail runs. TK are very confortable, light and they call for a playful fast paced run. However...a big disappointment is the heel of the shoe...both the upper and the sole. The upper needs some firm layer to protect the back of your feet against rocks. Also to hold the heel firmly to avoid undesired lateral movements...otherwise in uneven terrain you may be surprised when you notice a signficant portion of your heel is no longer on top of the sole but laterally displaced (....and yes, I do lace thightly to hold heels). The sole should be wider at the heel ...the rounded up outline looks nice but it gives up some precious-for-balance surface. A wonderful shoe with an appalling heel.

Comments: Nike finally comes up with a legit trail running shoe and a lower drop shoe and it is in the same great package. The light weight combined with a lower drop yet enough cushion make this shoe a good choice for many distances from short, fast trail races to longer ultras. The traction is good enough for most trails, but I wouldn't use it in wet, muddy conditions. The one thing I was nervous about was the soft heel counter. Very similar to that on the Free. I thought my heel would slip, or that I would have to lace them very tight. However, the heel actually fits very nice without having adjust the lacing. I just bought my second pair of these and will be logging many miles in this shoe in the months to come.

Comments: Wow, amazing shoe! I've always struggled to find a trail shoe that felt light, fast, and responsive while still maintaining enough protection, traction, and cushion for the trails. I've gone through all the race ready trail shoes from NB, Inov8, Brooks, Asics, Montrail, Hoka, Salomon, and Saucony, and Nike has really hit it out of the park with this one. The 4mm drop, extremly comfortable and airy upper, light weight, and responsive cushioning fit and feel similar to a road flat. The zoom cushioning in both front and rear of the shoe offer plenty of rock protection and a springy ride. The outsole offered great traction on technical trails and even felt good for stretches of pavement. The Salomon S-Lab Sense is close to a perfect shoe, but I feel a little too firm in the forefoot. This shoe picks up right where Salomon left off. I'd train and race in them for anything from 1 to 100 miles.

Comments: With so many great trail shoe options out there meeting the requirements of all running types, Nike was just lagging behind. Personally, I like around a 4mm drop and enough cushioning for long distances, but somewhat minimal as well. The old Brookes Puregrits were perfect for me. However, I was not a fan of the bottom on the new Puregrits. I have ran 2 training runs in the Terra Kinger's (10 miles and 15 miles) and did a 13.2M race in them. The verdict, I love them! Still need to be tested on longer runs with more technical trails, but I am not too concerned with their ability to hold up. If all goes well tomorrow on my 25 mile technical run, they will be coming along up to Waldo 100K. Nice job Nike!
