Sore feet - Insole advice

I have the G8 insoles which although are quite expensive have transformed my feet comfort on the bike.

They aren't perfect but are a world of difference from most of the flimsy standard insoles you normally get with shoes.

Without knowing what is wrong, it's hard to find the right fix. For me (probably Morton's neuroma, thanks a bunch Morton, you can have it back now) without a podiatrist in lockdown, I had to try a few things on a probability and cost basis, and it has got quite a bit better.

If doing it again I would start with shoes (given cleats well positioned and insoles in good nick) - are they wide enough? You can find wide ones on eBay that give you a cheap way to test - Lake, Bont and the wide-fitting Shimanos are a good place to start. I think narrow shoes caused my issue.

Then head for the specifics. For me, ball of foot cushions spread my metatarsals and that helps a lot. £8 for a pack on Amazon. Aimed at high heel wearers, about 50 mm across. Test alignment carefully as they can cause more pain if wrong. But this is where the podiatrist is probably worth the fee.

These were recommended to me: https://solestar.com/.

I've been using them for more than a year. I think they have helped, although my problems were not feet-specific, but more to do with joint alignment. 

I suffer with sore feet too. I used to get it all the time skiing, where your feet are in locked into position in ski boots all day, until I went and had a pair of boots professionally fitted which helped me understand what had been leading to the problems.

Pain or numbness in the foot is often caused when your sole is not properly in contact with the footbed. In my case this was because I have wide feet and the internal dimensions of the boot were not allowing my fore foot to spread naturally under increased downwards pressure. The fitter told me that all brands used different lasts and so fit differently. They told me there were only 2 brands I should consider for my feet which would suit me. I then also got a custom moulded insole to ensure the best platform inside the boots for my feet.

Even now I sometimes get the same sensations after a while when cycling if my laces are too tight in certain places (not allowing my feet to spread and maintain contact with the footbed) or my cleats are not aligned correctly (forcing too much pressure onto the outside of my foot) or the platform of the pedal is too small (although this could probably be helped by stiffer soles on the shoes).

Where do you experience the discomfort?

I have similar issues on rides over 200km despite insoles
IMO the issue is the very stiff carbon soles of my shoes. I'm planning to buy some cheaper nylon or composite soled shoes to use for along rides in the hope that alleviates the problem. I'm not going to be hammering it on rides that long so the power transfer argument is irrelevant for me in this case.
Sorry if this is no help.
