Saucony Kinvara 9 is good for performance runs by runners who want to feel light and fast. Saucony Freedom ISO 2 provides a plush ride and brings you closer to a neutral plane...

The Saucony Freedom ISO 2 and the Saucony Kinvara 9 are neutral running shoes for runners who do not need much stability and support and who prefer a more neutral running plane.

ADVERTISEMENTS

The uppers of the Saucony Freedom ISO 2 and the Saucony Kinvara 9 differ quite a bit in construction due to the fact that the Saucony Kinvara 9 does not have an ISOFIT upper.

The Saucony Freedom ISO 2 The preceding link takes you to Amazon.com combines ISOFIT with a knit upper, so it has these independent sections in the saddle that can be adjusted to fit your foot the way you want the upper to fit your foot.

The Saucony Kinvara 9 The preceding link takes you to Amazon.com is more basic in that it has a mesh upper with thin no-sew overlays that run from the saddle towards the back of the running shoe.

The Saucony Freedom ISO 2 also has some overlays around the midfoot, but these only go halfway towards the midsole so are more to support the individual sections in the saddle rather than to offer lots of support around the midfoot.

While the forefoot of both running shoes is quite open, the Saucony Kinvara 9 has some overlays running on the medial side, and the Saucony Freedom ISO 2 has the Saucony logo coming far forward towards the toe box.

However, both the Saucony Kinvara 9 and the Saucony Freedom ISO 2 should be able to provide a good amount of room to those who have big bunions or wide feet.

The back of the Saucony Kinvara 9 is more closed than that of the Saucony Freedom ISO 2, but whereas the Saucony Kinvara 9 has a woven area around the heel to deliver lightweight support, the Saucony Freedom ISO 2 comes with a Support Frame that hooks around the upper part of the heel to lock your heel in.

Therefore, the Saucony Freedom ISO 2 might provide a better and more secure heel fit than the Saucony Kinvara 9.

All in all, both the Saucony Kinvara 9 and the Saucony Freedom ISO 2 should be able to keep your foot on the running platform, and you should be able to get a good amount of comfort from either running shoe, but the Saucony Freedom ISO 2 provides a bit more personalization through its upper.

The midsoles of the Saucony Freedom ISO 2 and the Saucony Kinvara 9 differ in that the Saucony Kinvara 9 has an EVERUN topsole construction, while the Saucony Freedom ISO 2 has its entire midsole consisting of EVERUN cushioning.

Therefore, the Saucony Kinvara 9 delivers heel-to-toe cushioning just closer to the foot with more responsive cushioning in its midsole, while the Saucony Freedom ISO 2 is meant to deliver heel-to-toe plushness.

Saucony places the Saucony Freedom ISO 2 high on the plush cushioning scale, while the Saucony Kinvara 9 is placed high on the firm and responsive cushioning scale.

However, lab tests have not found the Saucony Kinvara 9 to deliver firm cushioning. On the contrary, the Saucony Kinvara 9 delivers an overall soft ride and provides somewhat more forefoot cushioning than heel cushioning.

The Saucony Freedom ISO 2 also delivers an overall soft ride and displays more balance between heel and forefoot cushioning.

So whether you choose to run in the Saucony Freedom ISO 2 or the Saucony Kinvara 9, you should be able to get a soft ride from either, with the Saucony Freedom ISO 2 perhaps feeling a bit more plush than the Saucony Kinvara 9.

Saucony lists both running shoes as having a relatively low heel-to-drop of 4 mm, so both running shoes are supposed to bring you closer to a neutral plane.

Lab tests have come up with different measurements that show that the Saucony Freedom ISO 2 has a slightly lower heel-to-drop than the Saucony Kinvara 9 for both men and women, but the difference is less than 1 mm.

Both the Saucony Kinvara 9 and the Saucony Freedom ISO 2 provide a good amount of ground contact, which adds some stability to the running shoes and helps you to achieve smoother heel-to-toe transitions.

While both running shoes can be seen as stable neutral running shoes, they probably do not deliver enough stability and support to overpronators and are meant to be worn by neutral runners who do not need much support.

The outsoles of the Saucony Freedom ISO 2 and the Saucony Kinvara 9 differ in that almost the entire outsole of the Saucony Freedom ISO 2 is covered by rubber, while the outsole of the Saucony Kinvara 9 only has rubber in high-wear areas, mostly to keep the weight of the running shoe down.

Therefore, the Saucony Freedom ISO 2 might turn out to be a bit more durable than the Saucony Kinvara 9.

Both running shoes display a zigzag pattern in the forefoot and have a small crash area under the heel to isolate impact at heel-strike.

Both the Saucony Freedom ISO 2 and the Saucony Kinvara 9 have been found to be stiff running shoes for both men and women, and the amount of stiffness is about the same in the two running shoes.

The Saucony Kinvara 9 is much lighter than the Saucony Freedom ISO 2 for both and women.

If you are a neutral runner who is looking for a soft, comfortable, and smooth ride from a running shoe that brings you closer to a horizontal plane, you could choose either the Saucony Freedom ISO 2 or the Saucony Kinvara 9.

The Saucony Kinvara 9 makes use of more basic materials and has been kept light to help you go fast, so it is a good running shoe to run a race, do uptempo runs, or do shorter runs.

The Saucony Freedom ISO 2 is a more luxurious running shoe that is meant to give you a plush ride, so it is good for longer runs.

Note: The weight of a running shoe depends on the size of the running shoe, so any weights mentioned in this review may differ from the weight of the running shoe you choose to wear. Running shoes of the same size were compared for this review.
