I have the MKS Lambda (aka Grip KIngs) pedals on my commuter, mtb and road bike. I love them. I've ridden in a variety of shoes with no slipping. I guess I'm too old to worry about what people think. I love to ride, and am a skilled rider. I just don't want to feel clipped in. I can keep up with my clipped in roadie friend, so I guess it's all good.
