foot pain

My Manager insists i wear safety shoes at work , for health and safety reasons ...I already suffer from neuropathy mostly at night which I control with co-codamol before bed ...However I have tried several makes of safety shoes and usually after a few hours it feels as if i am walking barefoot on a corrugated steel sheet , I have tried insoles but still have to find something to make them wearable , the only shoes i find comfortable for long periods are good old trainers as as the soles are very soft ...any ideas would be grateful ..i did ask my doctor , but she was no help ....

many Thanks

in the last 2 years i have tried several types , it seems that the soles are extremely hard , they have to be to comply with site safety . This causes me extreme discomfort after a few hours to the extent that i end up hobbling almost as if i have ball bearings in my shoes , insoles are of little help they just crease up after a few days and cause more problems also I tend to get attacks of neuropathy during the day with them which is extremely uncomfortable ...I just cannot afford to spend money and then to be unable to wear them ...at this moment I have 2 pairs which i cannot wear that totals nearly £80 wasted ...
