Any modification to make it not slide to the side while heavy pedaling? i almost want to change to other brand if problem still occur.
Just my experience: I used aerolites quite a bit about 15 years ago.
The cleats have a small lip on the inside and a larger stop on the outside (see the photo).
If you step down and engage the pedal without FIRST sliding your foot to the inside so that the outer end of the spindle is against the outer stop, the pedal will still engage and feel like it is locked, but the inner lip is really around the larger diameter of the spindle instead of off the inside edge of the spindle. In this case, there is only friction holding your foot from sliding outwards under hard pedaling forces.
If you make sure to get the inner lip properly off the inside of the spindle, the lip prevents your foot from sliding out.
It is subtle; and a verbal description sounds complicated; but it is really very simple. I know about this because I had the "sliding outward" problem a couple times until I looked closely and figured it out. It becomes a natural part of the clip-in foot motion.
I NEVER had aerolites just release directly. Those who do must either be incredibly strong or have a habit of "rolling" the foot in the plane along the pedal spindle while pedaling. Anyone who likes "no float" should consider aerolites, because they really have absolutely no float at all. Most systems have at least some flexibility in the rotational axis, even if there is no float angle. The aerolites are utterly
rigid in the rotational axis, because the cleat are screwed directly to the shoe and follow the entire length of the spindle.
I really liked them quite a bit and used them for racing for a full couple of years. I only switched because my knees were getting odd sore spots and I wanted to try floating pedals.
You can also lay sandpaper on the bottom of your shoe, and then rub the contact surface of the cleat against it untill the cleat contact surface mathches your shoe contour more closely if that is a problem.
