After working away the last two weeks in Barrow my feet are finished! I have been working long hours and I need to stop the pain

I have been wearing Caterpillar generator boots

The sides of my big toes are very swollen (not blistered) and unbearably painful at the point where the toe meets the foot

I don't want to post pics ;)

I will pay anything to have comfortable feet!

Any suggestions please!!! I have been recommended XR3s and was wondering about boots with external caps? composite caps may also be good

Help!
