RedWing Zinc Boots Recommendation

I'm considering buying RedWing Zinc boots, but they're more expensive than any shoe I've bought. I walk a lot and want to make sure I don't have to replace my shoes or spend money on sole replacements for at least another 8 years (for it to be cheaper to go with RedWings v.s. buying my cheap shoes every year). I like the style of the Zinc and the aggressive tread. I'd have liked the Blacksmith with the tread of the Zinc, but Zinc is fine overall. The steel toe isn't a deal-breaker or selling point for me. If anyone has any suggestions or recommendations I'm open to all options. If anyone has BIFL shoes that look like the Blacksmith with more aggressive tread (and hopefully cheaper) I'm open to that as well. I'm not wedded to RedWing, but I've heard good things.

P.S. How is their customer service, repair, warranty, etc?
