Comments: I agree with all other comments about the lack of cushion, especially in the forefoot. I've run in all Inspires since the 6 and the 10s are the firmest. I tried an experiment and ran with a new 10 on one foot and a 500+km 9 on the other and the difference in cushion was noticeable. The 10s feel much more dense and hard overall, but it is most noticeable in the forefoot. My legs feel beat-up the next day after running anything over 5km in the 10s. I really hope Mizuno remedy this in the next Inspire. I˙d happily sacrifice a little extra weight for softer cushioning- especially in the forefoot.

Comments: I too have had durability issues with these shoes. The first 200-250 miles (2 months) were great! But after 2 pair and developing forefoot problems, I have decided to switch shoes until there is a future model. The lack of cushioning and durability become very apparent once the shoes are worn in.

Comments: Agree with the other reviewers. Cushioning is not as good. Shoe is very lightweight (a plus), but durability has been compromised. I have holes wearing on both sides of both shoes where the upper meets the overlay at the toebox. My girlfriend has a pair and also has the same problem after only about 2 months of wear. And neither one of us is a heavy runner. Have loved Inspires for several years, but don't want to keep replacing them after a couple of months. Would appreciate a fix by Mizuno.

Comments: I have been an Inspire fan for years. I am disappointed with the #10 model for many of the same reasons. For me is durability, I have the big tears around the toes and the sides have torn like panty hose that get a runner in them. I used to get 500-600 miles on a pair of the older ones, not even 300 miles on these. I have had 2 pair so far. Plus the cushioning is a bit thinner. Gravel now hurts. I feel so lucky, my local runnung store had 1 more Inspire in my size. That will be awesome for a few months.

Comments: I like the light weight, but do no like the upper material. It is very abrasive and doesn't breathe as well which has caused me to develop calluses on both big toes. I have run in mizunos since 2009 and this is the first time I've had this problem.

Comments: After about 300 miles I have a small tear on the upper next to pinky toe where mesh and leather meet. I cant help but think that strength has been compromised by trying to make this shoe lighter. Or the movement in the front toe box which seems more open than wave inspire 9 maybe caused it. I still enjoyed running with this shoe.

Comments: The Toe box or front is too wide. This cause my foot to slip when I run and choke on my ankle. Its not so bad on flat courses. But on down hills it is an issue. I used to love the 9's. I still choose to run with this. But will look for similar shoes.;

Comments: I've used the Inspire 10 for two weeks so far and am very happy with them. All the earlier comments are true to an extent. The forefoot feels less cushioned but it's likely due to less toe spring than previous models. I run mainly on asphalt and cement, and the cushioning is noticeable once you get used to the feel. I'd say the cushioning is comparable to the Inspires 8 and 9 while there is a bit more stability and structure. The upper is stiffer than previously but it's also roomier. I use a medium weight sock in the Inspire 10 as opposed to lightweight socks in the 8 and 9. I do notice less give in the midfoot upper and need to be careful not to tighten the laces too much. But so far it is not an issue while running. The reduced weight and rounded edges on the outside make for a crisper ride. Time will tell if these will be as durable as the previous models but I have no reason to think they won't. I will continue to use these as my main high mileage shoe and prefer them over my l ast remaining pair of the 9.

Comments: I found the problem with this Inspire to be more in the upper of the shoe. Material has a stiffness as compared to previous models. Unfortunate, as I am a fan of Mizuno.
From: Tom, Indianapolis, IN
Comments: My experience is much more positive than the other reviews: this is my favorite shoe in quite a while. As noted, the forefoot is firm: however, I've found it to be very comfortable and responsive. Despite the apparent firmness, I found forefoot cushioning ample, and the shoe is considerably more structured than a racing shoe. For reference, I liked the Inspire 8, and found the fit and degree of control similar.
From: Marvin, Atlanta, GA, USA
Comments: Concur with the previous two reviews. Disappointed in the forefoot/ midfoot which, for me, is too firm even compared to the previous Inspire 9 model. Sure it's a considerably lighter shoe, but the sacrifice of the midsole (forefoot) cushioning would Not work for me. Glad I did try these on locally before ordering a pair!!!
From: David, Tempe, AZ
Comments: I completely agree with Nick from Philly's review of these shoes. The forefoot is very firm, and lacks adequate cushioning. The previous model had more cushioning. The upper fit is good, and the design and colors look great, but this shoe feels like a perfomance racing shoe with little/no forefoot cushioning, rather than a stability shoe. I really wanted to like this shoe as well.
From: Paul, NY, NY
Comments: I really wanted to like these shoes. The Inspire 10 has a really great upper, fit, and stability, but the midsole is way too firm in the forefoot. The 10 feels much less cushioned compared to the 9. This would have been a great shoe if Mizuno made the stack height 20/30mm instead of 17/30.
