KingGee K27951 Terra Firma Burnt Safety Boots

These are probably the most uncomfortable pair of work boots I have purcased. I tried a pair of King Gee boots for size at a 'bricks and mortar' store to get the right sizing. The boots I tried on and fitted well were size 8/9/42. The boots I purchased seemed to have been made to a different sizing scale. I have blisters, the nail on my second toe has turned black and the flexibilty in the boot is non existant, I might as well be wearing planks strapped to my feet. Certainly not happy
