I buy mine on Amazon. I've bought three of that pair. My first was repurposed to grass mowing after two years when my new dog ate some of the top. I still use it for mowing. My second wore out after two years because I starting a daily running routine with that dog.
I first started buying shoes online because my size (14) was very hard to find in stores. I usually could find only 2/3 different shoes per store. Now I have a lot more options.
