Speedplays
From what I understand from my main Bike Shope guy Kevin: float on speedplay clips is both up and down and side to side because they are a circle, the float is all over. I have Spd X/3 and love them. I started biking because running was killing my knee. The looks locked my foot in and still gave my knee fits. Kevin recommended speedplays and I do not have any pain in my knee now. The slight, very slight float helps my knee. And they are so easy to clip in and out.
Love them! I would recommend them to anyone!
