actually, the keo sprint has a lower spring tension than the other models. i rode the sprints last season (well half season) but i went a level up to the "carbon" model this year for track and put the "sprints" on my road bike. (seems kind of backwards, eh?.) the sprints go up to 15 Nm and the carbon and above models all go to 18 Nm and i have both pairs cranked all the way. i have yet to pull out of either, but im not exactly a watt monster like kevin mansker, and ill take the extra tension. also i feel more likely the pull out when using cleats with float for some reason.

> Look Keos. I use the "sprint" model because it has a higher max spring tension, and I tighten them as high as they go. It makes them hard to get into, but it also makes it hard to get out of, which inspires confidence, and confidence in your equipment is paramount. I concentrate mostly on sprint events, and I've never felt like I might pull out, even in standing starts. However, I HAVE seen people pull out on speedplays and spd's, for what its worth (not resulting in accidents, thankfully). I've also heard horror stories about crank bros setups releasing in a sprint. If the day comes that I think I might be strong enough to worry about my Looks, I know I can get clever with some hardware and zip ties and add a strap to them. I also use the black keo cleat for no float. I can't stand having float on the track, although I know plenty of people that use a +/- 4 degree cleat and don't find it to be a problem. Although I don't see anything wrong with using a traditional slotted cleat and a pedal with toe clips, I also don't see any benefits (unless you've already got that setup on your road bike and you'd like to share shoes between road and track). Road pedals, tightened down, work just fine, and although I'm new to the Alpenrose, I can tell you that's the sort of setup almost everybody at the 7-11 Velodrome in CO Springs was on, even the big Olympic Training Center sprinters (some with a strap, some without). I hope that was helpful, and I can't wait to see everybody on May 3rd!

I have seen many accidents caused by inadvertent detachment of the shoe from the pedal (even with clips and straps). I have never seen an injury directly because of a failure of the pedal to release in a fall. Some riders use pedals that have an SPD or other clip in mechanism AND straps on top of that. Some people have actually bolted the shoes to the pedals, although this is really only practical for top level timed events and sprints.

Probably a majority of track racers that race omnium events including the pros use the same Clipless pedals and thus same shoes as on their road bike.
>
> If you concerned or if you are accidentally pulling out with clipless pedals then they aren't adjusted correctly or you need pedals that offer more free rotation before release. By far the most secure pedals i have ever used were TIME mtb pedals, or Eggbeaters (the "two bar" type pedals, LOOK too now..), large float, they unclip easy but over at quite a large angle so never accidentally released. . My issue with them though is undefined and small pedal to shoe interface.
>
> If you are going to use Toe-and-Clip pedals with a slotted cleat, since there is no float or rotation, You must get the cleats aligned properly, preferably professionally or you will most likely hurt your knees. But even then, In the old days the shoes were fairly sloppy and so probably saved knees. if i recall correctly, As cycling shoe's heel cups stiffened, knee injuries increased. Depends on what sort of rotation you foot likes to do through a rotation. I had no issues when i first started on toe and clip pedals and a cleated slot shoe. But if i tried to go back now, i for sure would have issues...

> If you are going to use tennis / running shoes with Toe and Clip Pedals, it is rare but there is nothing wrong with this. Mass start Track racing is more about high spin speeds and thus low forces, so high shoe stiffness is not as critical as in other types of bicycle racing.

> 1. You want a clean no frills shoe with minimal tread (or remove with grinding wheel Wire Brush..) Something that cleanly and easily goes into the clip pedal. Stiff thin outer sole if you can get it, or you could maybe even find a stiff insole.. Err or you can do like did once with a fibrous insole... work in some fiberglass epoxy... thin and fairly stiff. .
>
> 2. And Pedals (if using a running shoe), you want probably almost a platform pedal that takes strap and clip. You want surface area, not a thin plate pedal as for a slotted cleat. You want to push with the ball of your foot and you want a nice flat surface to do this on..
>
> Keep in mind with Clip and Strap pedals, they might stick out a little further and you thus you have to be a little more mindful of clipping the Alpenrose banking at slow speeds. Also tuck in laces. Also since the races are short , the pain is short if for example the strap is digging into your foot.

> Check out Next Adventure and City Bikes, the latter usually has a nice collection of used shoes and pedals for cheap. For sure there are still purposely built toe and clip shoes for match sprinters. bike central ..
> Probably the most cost effective clipless pedals are the three hole Look Style. Not that i like them. Just make sure you replace the cleat when worn. I use to use shimano SPD pedals a lot (cause i like walkable shoes for commuting) But seemed to have issue with accidental release here and there.. and then once they didn't release until after my leg snapped. So not a fan anymore of Steel on Steel pedal to cleat.
