Different stages involved in the manufacture of industrial safety shoes ??

Whats the difference between the Goodyear Welted, Cemented and direct injection safety shoes ??

Different stages involved in the manufacture of industrial safety shoes ??
Yeah OSHA has all specs for safety gears, the welted one i dont know, the cemented one means sole and upper sole (leather part) are sticked together, where as direct injected PU sole (poly urethean (spell not sure)) means the Sole is moulded to the upper sole.
Reply:I don%26#039;t know, but if they follow the ASTM Z41 spec they are all essentially the same. My guess is from the names is that one has the hard toe as a continuous part of the shoe top, whereas the other is just a hard metal or plastic insert sewn in place.





Read the spec if you%26#039;re bored.
