Burn up the trail, not your feet.

Burn up the trails with Mavic’s rage-tastic Chasm Shoe. Power’s transferred to the pedals via an incredibly stiff carbon sole that sports tenacious traction lugs for mandatory hike-a-bikes. A pre-shaped, two-density insole cradles your heel for reduced blister-forming lift, while a well-vented tongue with EVA comfort insert prevents hot spots and manages moisture so your feet aren’t blazing.

Stiff shoes

These are very nice shoes. The carbon soles are as stiff as my highest end road shoes. These are as good as Sidi's highest end shoes for a third of the cost. I race single speed mountain bikes, so I need a stiff shoe with all the standing I end up doing. With Sidi Spider shoes, I could feel the soles flex around the pedal body. The carbon soles on these Mavics do not flex at all. For sizing, I wear a 10.5 US street shoe, and ride 44's in sidi's newer sizing (Sidi's got bigger in 2007ish, and I went from a 45 to a 44) In these shoes, I ordered a size 10 and they fit perfect. The toe box is a bit wider then sidi's making them a little bit more comfortable.

The only issue I have with these shoes are the upper material. With sidi's, they use a stiff leather like material, so there is very little movement resulting from material stretching. These shoes use a more breathable material that stretches quite a bit more, so when you pull up on the pedals, you do notice a little bit of movement. The other thing I'm a little weary of these shoes is the toe region. In Sidi's and Times that I've worn in the past, there is a little bit of a reinforcement in the toe area to give a little bit of protection when off the bike. This is a nice feature if you cyclocross. These shoes do not have much in that department. Would I buy again? The answer is Yes.

Good Shoe

I use this shoe on a road bike with SPD pedals. Very stiff, and even though a mtn shoe it is almost identical to the road shoe and includes the grippy walky stuff. I am not a cat 1 or 2 3 4 racer for that matter but i do ride hard training and group rides 150-200 miles per week. This shoe lets you get off the bike and have breakfast without slipping around or forgetting your cleat covers. Also great adjustment in the heel. my foot never slips and even after all day in RAGBRAI 60 miles on and off bike walking gravel and pavement etc eating pancakes no foot soreness. If toes swell just loosen the front adjustment. I think too many people try to fit in with the pack with a road shoe and overlook this option unless you are a crazy racer focused on liqht spinning weight.
