I guess I was one of the fortunate Chi-runners in Canada to have been invited by New Balance Canada to wear test and give feedback to their New Balance MR 800 MF (Mid-Foot Striking) last year, but due to allotment and sizing issues, I finally got my own pair from the rep just a few weeks ago. When NB Canada asked me if I wanted to test it, I said sure but to be honest with all of you, I was a bit skeptical. I read the reviews here and do respect the views and input of runners who ran with it and my bad experience with the NB 825 was something I dare not repeat again. Besides, I'm happy with my NB 790 and the Asics Hyperspeed and recently had gotten the Inov-8 Roclite, so I came into the testing with below the radar hopes. But when I tried it on my 2 tempo runs and today a long over 26 miles (44km) run, the shoes completely changed my mind. This is truly a great addition to my library of running shoes, especially as a "super high mileage" trainer.
Thank you New Balance for making such a great shoe for my needs and hope others..
Pros:
1, Very cushy, especially the orange thingy Abzorb foam they have on the side. My outside edge of the foot are usually a bit sore running 20 miles +. No soreness today beyond 20 miles + at all. Impressive.
2, Some sort of medial posting to resist collapsing on the ankle. Perhaps this is a good thing for overpronators like me if you start loosing your core stability on 20 miles + when you no longer able to keep pulling on the connective tissues to keep your ankles collapsing inwards, thus perhaps inflaming the tendons and ligaments around the ankle. With this shoes, I can feel my core starting to loose it past the 42km and I was basically sprinting the last few miles testing my core to the max and the shoes seemed to hold my feet in place very well. Thanks to the medial posting, my ankles are fine.
WARNING -- you should always and always rely on your core to level the pelvis to provide the stability you need to hold the ankles.. A bit of soreness on the legs, but gone now 2 hrs later.. Impressive!
3, Toe down bias. It seemed, like my Inov-8, that it makes my toes put downwards. So you need to pull your heel a bit higher so you don't trip as you swing your driving hips forward. But I guess the good news is that, you land midfoot. Close to a 100k, the heel section of the shoes have no abrasion marks. Good news..
4, Fitting is very similar to my New Balance 790 Z3 version (the 2E sizing). Very roomy on the toes section. The regular NB 790 D version is a bit tight.
5, Did I tell that you can pretty run with these things forever? When I reached the 44km (I was planning for only 23 miles), I wanted to go further. My supply Pepsi on the hydration belt were gone. Perhaps if I stop by a convenience store somewhere and get a 355ml Pepsi can, I could probably go another 6km or so. But I just don't want to tempt my faith. But this certainly solidified my confidence that, I could actually do the whole marathon, one coming up in about 2 months should be a walk in the park. Hope.
6, Good for people who tend to ankle invert?! I felt that there's this wedge thing on the outside of the shoes and it seemed to help my left foot, which besides being an overpronator but also tends to land at a scary angle. This wedge thing seemed to have helped assist that. The ankles felt so much better after 26 miles, so something must be helping my foot stabilize. I tried to run on the nasty sides of the road and not the crown, and it's doing a pretty good job stabilizing my weakest foot. That's probably I pushed hard by leaning forward and blast the last miles -- no pain but all the gain?
7, No blisters and the flatness of the shoes gave an equal pressure on my foot bed. That's really what I need!
Cons:
1, It's heavy and not as responsive as my Asics Hyperspeed or the NB790.
2, It's a bit stiffer than I would like and not as flexible as my Roclite 315. But perhaps, a Chi-running newbie will benefit from this.
3, It gets dirty too easily. But I guess, that's why it's called a running shoe.
I promise NB Canada to wear test and share my findings with everyone. I am just one view of the many wear testers who have these shoes. I hope that by sharing my experiences with all of you, some of you may benefit from running with these shoes.
I'll be running 1/2 and full marathons with these this year. Very exciting. Will see how long these things will last comfort wise as well..
More observations to come..
David.
