The outsole is comprised of the Easton EC90 unidirectional carbon sole for stiffness and power, a grippy set of tall dual-density lug’s for traction, and a mid-foot scuff guard for grip when not clipped-in, and to protect the carbon. The upper is made from the tough synthetic Teijin microfiber, and includes a warp around welded scuff guard for durability, well padded tongue, and for closure, it uses a ratcheting buckle, and offset Velcro straps to alleviate pressure spots. The insole uses their SuperNatural Fit Kit, which has an adjustable arch support system for tuning and fit, and has X-Static anti-microbial fiber material for wicking and odor control. They come in White/Black, Black and Magnesium/Black colors, and are available in full sizes from 39-48, and half sizes from 39.5-46.5, and weigh approximately 355 grams each.
I was amazed at how much power and leverage I could pry out of the shoes, and it helped with acceleration, traction, balance, and lessened fatigue. The thin sole is stiff, and the low stack height translates into a superb tactile feeling, giving one additional feedback, response and precision. The EC90 carbon sole has some pretty nice qualities, which really help the shoe’s characteristics.
The toe bash and side scuff guards, along with the wrap around protection do an impressive job, and save the foot from injury and impacts, and mostly keep the shoe from getting destroyed and abraded. I regularly tested this system, and it kept my feet from getting smashed and hurt from rocks and tree branches. The bottom carbon plate has gotten some scratches and gouges from riding and hiking, but they seem fine for the abusive wear I have tossed at them. I am an absolute shoe destroyer, and except for some premature wear on the front toe lugs and scuff guards, they have been durable. The base Teijin microfiber works in great synergy with the scuff guards to provide comfort, snugness and a bombproof layer to protect you from the outside world.
They have gotten accelerated wear under the toe’s and front scuff guard, and I have pretty much worn down the front lugs to nubbins, which was exacerbated from my extensive hiking on rocky terrain. The scuff guards have some cuts and worn through marks, but it’s mostly cosmetic and superficial, and the underlying material seems to be protected? The lugs sometimes chunk off in peeling pieces as they wear, which can cause some premature wearing in spots, especially around the edges of their platforms, although the main stack height seems more robust. The lugs aren’t made from the stickiest rubber compound, so you can slide on smooth rocks, although their hardness does help their longevity underneath the foot, but they still have an average tread life. There was plenty of room for cleats between the lugs, and I had no interference issue with Shimano SPD pedals.
