Over-the-counter insoles are neutral footbeds, so you just need to pick the one that works for you. There are plenty out there, so don't think you have to chose just one. If it doesn't work for you, take it back to the store. (if it's a Superfeet, you have 60 days to return it. If your store won't take it back, contact Superfeet directly.)
Berry Superfeet are nice for biking, because they have a fairly juicy metatarsal button built into them and a softer met weightbearing surface. They are midway between the green (very stablilzing) and the blue (softer and more flexible) Superfeets.
Bear in mind that Superfeet modified specifically for biking problems/issues should have forefoot additions: probably a medial forefoot wedge of 3, 4, or 5 degrees, and likely a real met button. (much beefier than the one in Berry Superfeet) Met buttons should be placed after you've been wearing the insoles a while and have developed a wear pattern. When you get into the hefty met buttons, individual placement patterns are very important. (My biking Superfeet are Greens, with met buttons and forefoot wedges added. I need a LOT of firm support and a very deep heelcup.)
Insoles shouldn't drastically change the fit of your shoes, just be sure to take out the sockliner the shoes came with before you put the insole in. If your PT posts your insoles, that's a different ball of wax. I save my older, more broken down (and therefore thinner) insoles for my slip-on shoes, because you can't adjust the tightness of a slip-on so manufacturers tend to make them on a snug last.
Sockliners tend to be like the saddles on new bikes: no-one actually expects the person to keep the darn thing, so they don't spend the money to put a good one on, cuz what's good for one person won't be good for the next. Insoles are incredibly individual, just like bike saddles. When you find one you like, go for it! If you try one (and always take at least 2 pair of shoes with when insole shopping) and hate it, DON'T BUY IT! It won't feel better later!
There are insoles for high-heels, dress shoes, casual, sport, and so on.
The only thing I really don't recommend are the heat-molded OTC's. If anything is being custom molded to your feet, please let it be done by a licensed Orthotist. (which I am not, and know it!) If you need to find an orthotist, ask your doc or PT who they recommend. A really good orthotist will watch you walk, make you do functional activities, etc in their lab. They will mold your feet and then make you orthotics based on what they have seen. They will *also* let you come back for re-fits. And they will try to bill your insurance. (many insurances fight paying for orthotics, which drives me nuts)
