I ride the North East which means rocks roots and mud, and these pedals have been flawless. No issues clipping in or out on very muddy rides. Bashed them on rocks with no problems. They have always released when i wanted them to. The seals around the axle seems very tight and keep all the crap out.
One nice feature is that the float is separate from spring tension. Meaning you get the same amount of float no matter how much force you choose to have to use to release. Unlike other pedals.
If i had to do it again, i would still buy these pedals. highly recommended.
