Professional mechanics pay top dollar for quality tools like Snap On because they earn a living with those tools and a cheap tool that breaks is not a bargain.
We earn our living on our feet, so going cheap on footwear isnt a bargain either--at least not if you plan on making a career here.
The demands of our job are such that you really do get what you pay for when it comes to footwear. I will blow out a cheap pair of shoes or boots in a matter of weeks, and my feet and knees and back will also pay the price. Instead, I invest $250 in a pair of Danner boots and budget to have them resoled/reconditioned once a year for about $120.
There are lots of things that you can get away with cutting corners on, but footwear isnt one of them when you get in and out of a package car 200 times a day handling many thousands of pounds. Do your body a favor and invest in quality footwear-your body will thank you in the long run.
