My main concern is comfort. I really like the CATERPILLAR FLEXION sole with soft toe. The sole flexes a lot which helps if you have to swat down or kneel a lot while working. As another member mentioned the steel toe/ composite toe shoes cause a little too much discomfort. Here is the link to the shoe:
