Very simply how did it go and how hard was it ?
Pics would be great.
Also if you you have used a speedplay cleat extender
I would like to hear how that went.
cheers
very easy - did it for a friend to several pairs of shoes. she was using spd’s on her road bike and i gave her about 1/2 inch adjustment, and pulled them back about an inch.
spd’s would be easiest as they are so short, front to back.
i think 5mm drill bit and a round needle file
yep - don’t have any pics though. The original holes had metal threads inset into the sole. I placed star nuts inside the shoe so that the cleat bolts were placing a compression force on the sole (no risk of delaminating). I’ve done the same with another set of Bont’s - Bont actual do the orginal drilling with star nuts inside the shoes, so I just drilled a second set of holes further back and moved the star nuts.
thanks guys !!!
And yes the star nut system seems like the easiest and safest way to do it.
Thanks again.

Ps last question how much “meat” carbon should one have around ones drilling. on my clients shoes there is a vent that starts around 2 cm back from the original drilled holes how close can i safely go ?
I recently moved my cleats to mid-foot. It worked great. Unfortunately, I took the chance because my old shoes were dying anyway. Who cares if I do a little experiment on them if they need to be replaced anyways, right? Well, the experiment went well, but I still am going to need to replace those shoes.
Like you, I am noticing that the new shoes do not seem to be good candidates for mid-sole drilling. Some have vents like you talk about and some just have an indention there. Either way its a problem. I don’t believe the shoes need that much “meat”. Carbon is pretty strong. However, you need a good surface for your shoe/cleat/pedal interface and I just don’t see it happening on these types of shoes. I would be interested in seeing any photos as well.
Like others here, I just reused my existing bolts once I had drilled my new holes. I use eggbeater cleats and pedals. They are cheap. The are light. They are a bit difficult to get into the pedal (that could be just me and just the mid-foot aspect). However, I don’t care about getting into the pedal that much because in a triathlon I am never clipping in or out. I found the overall setup to be a bit better for my biking and better for my run.

Here is my video that shows a couple of options with regard to moving your cleats backward… Speedplay Rear Extension, custom drilled, etc…
Nice video! I am about two weeks into using an old pair of Shimano tri-bike shoes with mid-foot spd; and I agree with all of your observations on power gain. Did a brick yesterday and it felt like I hadn’t just jumped of the bike after a hard set of VO2 intervals… Hadn’t heard of anyone putting speedplays in the mid-foot and that might be worth a try (won’t work with some soles that have the vent thing going on).
If anyone is thinking of doing this, beware of the lateral placement – my left shoe rubs just a little bit on the crank arm. Got a new pair of tri-shoes coming (old pair is too tight anyway) and looking forward to taking up the FTP!
What pedals do you use with your SPD cleated shoes?
Do you have a list of other SPD pedals that you might use for road/tri usage?

After years of having my cleats not far back enough I finally started drilling my shoes. After about 8 years of this I finally did what I should have done a long time ago and switched from SPD-SL to Speedplay with the extender system. It works well and my feet are in the right spot now.
I use the Speedplay cleat extenders on both my road and tri shoes. This allowed me to shift my foot forward to a position where I don’t get foot pain any more. I’m 100% happy with them.
i have a speedplay extender for sale if ya want one! 
I actually was testing some cheap M520 mtn bike pedals with the SPD mid-sole cleat… It worked great and was very cheap

Thanks.
Any solutions or recommendations like this for looks?
I’ve never actually tried. But from what I’ve read (Joe Friel’s blog, among other places), the Speedplay extenders don’t allow you to go to a true midfoot (ie. at the arch) cleat position, though. Are you saying otherwise?

Midfoot? At the arch? I’ve not heard of putting the foot that far over the spindle and no, the Speedplay system does not allow that kind of extension. I had a nagging piriformis problem for years until I started drilling my shoes to get the cleat further back. I’m glad to have it behind me now with a simpler solution.
Any solutions or recommendations like this for looks?
I use Looks and just move the cleats back by drilling a second set of holes in the soles. Depending on the sole you may not be able to get a midfoot mount, but I have been able to move cleats 25mm further back on 3 sets of different shoes. I have never seen an adapter plate for Looks.
any chance you could send me some pictures @ johnpaul9637@gmail.com?
Curve of the sole and narrowing of the sole under the arch prevents the cleat from being moved further back on these shoes. I also have a set of Bonts (not pictured) that have a much flatter, wider sole that would be suitable for a midfoot mount http://i1285.photobucket.com/albums/a597/nickag1/dee47cffa137fa375aeac60752a09663_zps254d01ac.jpg
You can see the original holes just above the cleats. The cleat overhangs the inside of the sole by about 10mm (this is the right shoe).

Not visible from photo, but the star/T nut protrudes into the shoe, the insole goes over the nuts and covers them up so doesn’t cause me any problems.
