Good Morning DKSF,
While I have no experience with that particular North Face model, I did spend several hundred miles training miles in a North Face shoe designed for 100 miler’s. I was disappointed in the quality and ended-up taking the shoe into the SF North Face store to discuss the matter. To their credit, they agreed with me and refunded my money. I continue to buy North Face products without reservation and think well of the company as a whole.
Shoe selection is critical and what I found was that the characteristics I needed in a trail running shoe were very different than in my regular training road shoes. At WS the devil for me was the 20,000’ feet of elevation drop! I ended up running hilly Ultra’s (including WS100) in Montrails and continue to be a “Vitesse” fan, which makes me a bit of a Ludite. I used two pair: one for the start and one on the other side of the river crossing.
*** One thing that you should consider is the use of gaiters to keep out small rocks, grit, and thorns and to minimize the accumulation of dirt. Joe Dana makes some that are wonderful and do not have a bothersome strap that wraps around the shoe www.joetrailman.com
Your note gave me pause to reflect a bit and laugh at myself. My journey into Ultra running began with a call from a buddy asking me to pace him at WS - I had no real idea as to what it was. I was at peak fitness, and a bit full of myself, for the old (Full) IM CA, bulletproof and casually committed a “sure … sounds like fun” without a care or inquiry as to any of the details other than the date June 23-24. Long story short I raced very hard at IMCA that May, blacking out in the final miles of the run, posting an AG 2 to Don Fink’s 1 and was absolutely physically crushed. I was a complete WRECK! after two weeks of recovery I could barely “trot” 10K, flat, without crashing out.
I began to worry about my pacing job! Under the guise of a very causual “hey, how are you? Are you getting excited …” call I rang my buddy to investigate just “what” this “pacing” job was all about without letting on that I was such a wreck. I almost fell out of my chair when he mentioned that I would run with him from Foresthill to Augurn - 38 miles!!
I ended up have in blast although I was completely ignorant (stupid would also work) in any, and all, things “Ultra” - I ended up doing a great job for him and following the finish I thought: “I gotta get some of this!” I took two years off my Ironman focus to do it.
. . . Oh, the shoes I paced in: Asics DS Trainers 
Truth.
The lower portion of WS is not so bad as the first 62. Plan on hot, dusty and epic good fun.
