A great option
This is my 3rd pair, and I will keep buying them. They fit me perfectly and are extremely comfortable to be in all day. They're fairly light weight, with good grip compared to one particular other brand I have used. The trade off is that they last around 2 years of work before the soles wear through the tread, but I could wear them longer. Notes - I work on a surfaced workshop floor, which may reduce the wear rate. Also my first pair bought when FXD was a new brand started to fail around the sides of the toe cap of both left and right sides after 20 months of more vigorous work. This has not been a problem with subsequent ones.
Overall I think that's a very reasonable life for the cost of the product. I recommend FXD to others I work with and they have been happy too.
