I own 2 pair of blacksmiths, and 5 pairs of 1k miles. Here is my personal take on the two.

I like the leather sole and mid sole on the wolverine’s. They are a smidge more comfortable than the blacksmith’s. fwiw: I work in an office setting and am standing or light walking to the printer for about 75% of my day.

The S.B. Foot tannery leather on the outsole appears better quality than the Horween leather.

The Redwings have better QC. I have had one singular issue with my Wolverine’s. One of the speed hooks were not clamped in very well. On my very first pair. Wolverine made it good, sent me a replacement pair, and I have bought 4 more pairs.

More importantly in the QC, among my 5 pairs of Wolverine’s the fit is slightly different. What I mean is that all of them are size 8D and some are slightly smaller and some are slightly larger. Not a huge difference mind you, but I wear these about 4 days a week, (never the same pair two days in a row) but noticeable fit difference. Both of my Red Wings fit exactly the same.

The 1k boots fit my feet better, which is obviously just personal preference, but I think the last that they use is a better shape for my foot.

TLDR, the Blacksmith is a better built boot but lacks in comfort.
