We recently traded in our Nike ACG trail running shoes for the Adidas Kumasi XCRs. We had beaten the Nikes to a pulp and it was time to try something new.
We got a pair of the regular Adidas Kumasi and a pair of the Kumasi XCR. The regular Kumasi and the XCR differs only in that the XCR has Gore-Tex uppers and are seam-sealed for complete waterproof protection.
One of the most important considerations for choosing a pair of trail running shoes are traction and support.
The Kumasi shoe has an aggressive tread pattern with excellent gripping rubber. Incorporated into the sole is a plate which offers "push through" protection from sharp rocks and other trail hazzards.
Most hiking shoes offer support and traction at the expense of weight. Normal running shoes are light but are designed to support forward movement. Trail running shoes need to have stability support in all directions AND be as light as possible.
The Adidas Kumasi is pretty light, weighing in at 15 ounces per shoe. It is about as light as the designers could go with the materials while still making the shoe durable enough for trail use. The Nike ACG we had was 17 oz each.
The Torsion® System at midfoot supports and allows for the natural rotation between heel and forefoot, and allows the runner better surface adaptability. Note the channel along the heel in the photo below, the channel allows the heel to a bit more flexible, independent of the midsole.
The lacing and the seude exterior of the Kumasi are very similar to most hiking footwear. The material is abrasion resistant and in the XCR, waterproof.
In the XCR model, the Gore-Tex upper and waterproof lining means this shoe will be excellent for typical, muddy, New England trails!
The Gore-Tex feature also means the shoe will be breathable as well... an important feature for trail runners who like to run no matter what the conditions are outside.
We are looking forward to taking these shoes out for their FirstUse test. We'll report back after we have had a chance to try them out!
