Saucony Kinvara 7 Review

Saucony Kinvara 7 General Info

Saucony Kinvara 7 – Medial Side

The $110 Kinvara 7 weighs in at 6.6oz for women (size 8) and 7.7oz for men (size 9) with 4mm heel-to-toe differential (18mm forefoot, 22mm heel.

The fit of version 7 remains unchanged from version 6 with an adequate, but not particularly wide toe box, and a snug midfoot feel. This version runs true to size.

The Kinvara 7 was tested on paved roads and groomed gravel trails. It performed well on long runs, quick tempos, and everything in between.

While several substantial changes in the shoe’s technology have been made, the general character of version 7 remains true to the Kinvara experience.

Although the placement pattern has changed slightly, the Kinvara 7 continues to employ injection blown rubber in strategic zones on the sole in order to keep the weight of the shoe down while providing optimal durability and protection in areas where the highest ground contact occurs.

Strategic placement of injection blown rubber under the forefoot and along the lateral arch in the TRI-FLEX configuration provides traction and durability while distributing shock more evenly across the sole.

Saucony has replaced the PowerGrid EVA+ foam platform with resilient EverRun SSL that is significantly more dense and more firm than previous models.

EverRun is intended to maintain its integrity longer than standard EVA foam; and with its introduction, I expect version 7 to be the most durable Kinvara to date.

These changes have undoubtedly impacted the ride of the shoe. On my first run in the Kinvara 7, I felt a noticeable difference in the softness of the ride.

While the Kinvara 6 and earlier versions boasted a soft, luxurious ride, the Kinvara 7 is much more firm. The shoe feels as if the stack height is higher than in version 6, but it is exactly the same.

I attribute this feeling to the firmness. The Kinvara 7 is much less forgiving than the 6.

My first few runs in this shoe on the road felt quite stiff underfoot I could audibly hear my foot slap the pavement; a phenomenon I never experienced in the 6. Unlike the 6, the 7 requires a few miles of break-in before it starts to feel natural underfoot.

Saucony Kinvara 7 Upper Info

Saucony Kinvara 7 – Top

The upper of the Kinvara 7 carries over the two predominant technical features of version 6: FlexFilm and the Pro-Lock lacing system.

The FlexFilm overlays are melded to the upper of the shoe to eliminate seams. Flex Film stiffens the upper, but retains enough flexibility to be comfortable.

I have to admit, I was disappointed to see the Pro-Lock lacing system reappear in this version because I find it unnecessary and even constrictive.

The first time I wore the Kinvara 6 I had to stop 30 minutes into the run to loosen the laces and Pro-Lock pieces, which sit underneath the main upper unit, but on top of the tongue, because my foot had gone numb.

After experiencing this discomfort with version 6, I knew to keep the middle laces loose and thus avoided those problems with version 7. The upper of the Kinvara is snug as it is, and so the Pro-Lock lacing is unneeded.

However, this technical component persists, so for runners with a lower arch or wider foot, the overly-tight Pro-Lock system could cause significant discomfort.

Despite this issue, the toe-box of the Kinvara 7 was adequate as in previous models.The heel counter is soft and forgiving where it makes contact against the Achilles.
