I don't, but the bottom of my feet don't have the same angle w/ my legs that the average person has. After a few injuries and subsequent issues with foot pain in my shoes, I had my feet scanned at Footfitting, which is now eSoles. They made a custom pair of footbeds for me, that include the proper varus wedge for one foot and valgus wedge for the other. As such, I use Specialized wedges (plastic shims that go under the footbeds) to null the varus wedge built into Specialized shoes.
Specialized have a 1.5mm varus wedge, which means inside edge of their lasts is 1.5mm higher than the outside. According to the doc that did the research upon which Specialized's lasts are designed, the average person has about 1.5mm of varus wedge. The varus wedge does not cause the foot to slip, but for people with about 1.5mm of varus wedge, it distributes the pressure generated when pedaling more evenly across the bottom of the foot. The wedge isn't so much that your foot will slip. 1.5mm of wedge on the last only creates an angle of about 0.85°. If you're foot doesn't get on with the inbuilt varus wedge, Specialized make shims (as I mentioned above) that you can use to null that wedge or to introduce valgus wedge or more varus wedge. Most folks I know have zero issues with the inbuilt wedge. FWIW, I believe the Specialized wedge kit gives you the ability to change their wedge by 3mm. So, you can go from 4.5mm of varus wedge to -1.5mm of valgus wedge.
What you might feel if your foot isn't enjoying the angle of a given last is foot pain localized on the bottom of the foot on either the medial or lateral sides of the sole of your foot. You might get numbness, and you also might get knee pain. Again, most people don't have an issue. Mine was an odd cause, that was either caused by genetic luck, traumatic remodeling of my feet and legs, or both.
