First of all make sure your shoes are not too tight, if they have velcro straps loosen them a bit and if you have laces, moving the laces up from the bottom one hole might give you some extra wiggle room. I spent $300 on nice Sidi shoes to get rid of my numbness but unless I put arch supports inside them, the numbness came back. If I wear thicker socks my feet will go numb again. A lot of the issue is going to be trial and error. Everyone is different.
