I can't speak to that particular boot but as a Dish customer (other than installing my own dishes for FTA), I would recommend something that's comfortable--for your feet's sake

--but is also easy to clean and/or take off before entering a customer's premises. I personally would look for something that has no or few nooks and crannies where dirt/mud/snow/grass/etc. can get trapped and difficult to remove.
A good pair of overboots can be a great help with that as well if the weather has been wet or snowy. I know my wife doesn't want to see my dirty boots go beyond the mud room, if THAT far! It would be upsetting to me if a tech tramped dirt into my house when it could've been easily avoided.
Good luck with the new work!
