Saucony Kinvara 8
Update: See our full review of the Kinvara 8 with comparisons to Kinvara 7 and others here
I have now run about 20 miles in the upcoming Kinvara 8, all on a fairly firm indoor track at slower tempo paces,
This is a very good update solving some of the issues of the Kinvara 7 (RTR review here): overly snug mid foot hold and stiffness. It can be called a smart step back towards the original Kinvaras without going all the way back to being super flexible with a largely unstructured upper, and soft ride.
At the midfoot, the Pro-Lock straps hold the foot down just right, no longer "in the way" and overly constraining but still there functioning more like Saucony's IOS Fit,
The upper is a single material, soft mesh with melted on Pro-Film overlays. It should be very breathable.
Update: After running a Kinvara 7 on one foot and a Kinvara 8 on the other and closely examining the firmness of the midsole, I find the Kinvara 7 has a firmer midsole foam and ride than the 8, I am now concluding that the Kinvara 8 is softer in the heel and forefoot than the Kinvara 7. The heel of the Kinvara 7 even with its Everun insert is firmer and more responsive than the Kinvara 8. The forefoot of the Kinvara 8 is more agile and flexible as instead of a conventional "board" below the sock liner it has the softer 3mm Everun layer.
The ride is very good, stable and smooth, decently responsive but on the soft side particularly at the heel. The Kinvara 7 is stiffer while the Kinvara 8 after 10 miles was more flexible, far more agile feeling.
Update: The Kinvara 7 is a firmer, stiffer overall ride and is a slightly more responsive, faster feeling shoe. The Kinvara 8 is softer overall, more training focused and yet has a slightly more agile and natural ride due to its improved forefoot flexibility and more minimal yet still foot conforming upper which still has a fairly snug but more relaxed mid foot hold.
The Kinvara 8 so far represents a blend of the Kinvara 7's snug mid-foot support, now dialed down and more comfortable, along with the more flexible accommodating front of the shoe of the earlier Kinvara on top of a softer, maybe a touch to soft for my tastes. riding midsole.
