Mongooser... i am not sure if you are on a Mongoose or not. It could be 3 things if you like your flats. 1. Running normal takkies and not quite grippy pedals: Look into a set of 5.10 shoes. Also look at pedals with threaded/slightly longer pins. Get thin concave pedals and all of the above. Thats pretty much as grippy as it will get. 2. It could be technique. Maybe get some advice from another local DHer. Let them follow you down a trail and tell you what you can improve on. 3. A Mongoose Booter: Not dissing bikes here at all, but the floating BB/crank on a Booter causes the crank/pedals to move back and forth under compressions. So your pins in the pedals never quite settle into the grip of the shoe. Even Pottie swopped from flats to clips when he moved from Cannondale to Mongoose back in 2007/8. He grated away a set of 5.10 Impact lows in a bit more than a month.
