I plan to try on different pairs from different brands in Japan just to see. And then maybe try to get a used pair once I figure out sizing. But definitely taking heel slip and the unique fit of engineers into consideration.If you have never tried Engineers before, you need to try several pairs on first, in order to get an idea of fit, heel slip and walking traits before you worry about the leather you want. Get the fit right first (and really know what your feet are both a Brannock device and in a few pairs of boots), then sort out the more appearance-based parts of the boots and their "living with it" realities. Engineers are unique in terms of fit to lace-up work boots or pull-on cowboy boots.
The Wesco 7400 Engineers I have on my feet right now are the third pair of Wesco's I have owned since a pair of Mr Lou's passed through my feet (a great fit but a challenging walk to them for me). This pair is pre-owned, I have no idea if they are horsehide or steerhide, but my feet absolutely do not care. They are very comfortable and easy to wear anytime. I would far rather have that than an "ideal" leather on a boot that is uncomfortable and that I do not want to wear. This pair was also $400 shipped.
