As
@User13710 says, the tightness of your shoes is key. If you have a bit of toe wiggle room, then a pair of woolly socks, or a couple of pairs of not too tight socks should help. And also the windproofness of your shoes (remember they are moving all the time so get a bit of wind chill).
Also, you might want to try chemical footwarmers that you can get from
Decathlon and other outdoor shops.
