When you want performance and protection without extra weight, the Nike ACG Air Thielsen is the optimal choice for training or racing on trails and uneven terrain. The upper incorporates a lightweight mono sock with breathable mesh vents and polyurethane-coated leather, shaving ounces off the overall weight, especially when you compare it to trail running shoes with similar profiles. An internal shank enhances torsional rigidity without weighing down the shoe.
Great Shoes
The shoes are great, the fit everywhere and comform to my feet when walking. The tread on the shoe really helps my feet from slipping and the shoe is still light even with the knobby tread. I am overall very excited with the purchase of these shoes.
Quality, comfortable, pretty, slow to take off/on
Very high quality, very comfortable -- no break it at all, attractive. What I wanted. Is a little time-consuming to put on/take off.
a good looking, comfortable, well-made shoe
I have a great deal of trouble finding shoes that fit - narrow heels, wide forefoot, high arches, lots of injuries. A friend told me about the Nike Air Thielsens - and they fit! I can actually wear them all day - they are quite comfortable. I look forward to wearing them a long time, as my friend, who is a super - marathon runner and hard on her shoes, says they are very durable.

killer shoes for trail
Just bought a second pair- wore the first ones out. 'nuff said. Read the other reviews for more details. I love the shoes and highly recommend em.
Speed, Traction and Comfort!!!
I compete in Dog Agility (obstacle course competition). We run on many surfaces-wet grass, packed dirt, carpet, sand-you name it.
I not only need to accelerate and decelerate
quickly, but there are sudden and sharp direction changes. Even in mud, I am confident in my traction and shoes performance. When you're confident, you win.
I like them too
I had an Achilles tendon problem that was keeping me from running. When I switched from Saucony Shadows to the Thielsens, the problen went away. I like the wider toe box and narrow heel. Fits great. Only complaint is their price.
Perfect Lightweight Trailrunning Shoe!
I have always been a dedicated wearer of Nike footwear, but it was not until I tried the Air Thielsen's that I realized just how far Nike has come in their designs. This shoe is the ultimate in comfort, fit and style. Not only is it super lightweight, but it also has a wider toebox, enabling the foot to breathe and stretch a little better. I am thoroughly convinced that this is the trailrunner of the future!
