Saucony Redeemer offers maximum pronation control and a very plush ride to severe overpronators. Saucony Stabil CS3 is relatively light with tons of stability and cushioning.
The Saucony Redeemer and the Saucony Stabil CS3 are motion control running shoes that are geared toward severe overpronators.
The upper of the Saucony Stabil CS3 consists of sturdy stitched-on overlays on both sides of the shoe with broader overlays on the medial side than on the lateral side.
The Saucony Redeemer on the other hand, has broad ISOFIT overlays on both sides of the shoe that wraps around the midfoot to provide support there.
And then there are no-sew overlays running over the toe box to provide structure there.
At the back, the Saucony Redeemer ISO comes with a sturdy Support Frame to keep your heel firmly in place.
While the Saucony Stabil CS3 also comes with a support frame, it does not wrap the heel as the one in the Saucony Redeemer ISO, but rather cups it on two sides.
All in all, you can expect to get a lot of support from the upper from both running shoes, with the amount coming from the Saucony Redeemer ISO being just a tad bit more.
Both the Saucony Stabil CS3 and the Saucony Redeemer ISO provide heel-to-toe cushioning through their midsoles with the difference that the midsole of the Saucony Redeemer ISO is the updated version of that of the Saucony Stabil CS3, so newer.
Both running shoes also have a crash pad under the heel that runs till the midfoot to soften your landings and provide you with a smooth transition to toe-off.
However, the crash pad of the Saucony Redeemer ISO joins the forefoot more seamlessly than that of the Saucony Stabil CS3 and provides better ground contact in that area, making the Saucony Redeemer ISO more likely to give you a smoother ride.
The Saucony Stabil CS3 is known to be a cushy running shoe, but running shoe lab tests show that the Saucony Redeemer ISO is overall much more cushy than the Saucony Stabil CS3, especially for men.
For women, the amount of cushioning comes close to each other, but the Saucony Redeemer ISO is still more cushy than the Saucony Stabil CS3, especially in the heel.
The Saucony Redeemer ISO delivers maximum cushioning in the forefoot for both women and men, and has a very cushy heel, so you can expect to get a soft running experience from this motion control running shoe.
On the medial side of the midsole, both running shoes have a large, long, and sturdy piece of firmer foam to stop the feet of severe overpronators from rolling too far inward.
This medial post is more squarish at the beginning and end in the Saucony Redeemer ISO than it is in the Saucony Stabil CS3, so it covers a slightly larger area.
The medial post of the Saucony Redeemer ISO also comes with vertical pillars stuck in the foam to provide more reinforcement. The Saucony Stabil CS3 just has the firmer piece of foam.
When you compare the bottom of the shoes, it is clearly visible how large the area of pronation control in the Saucony Redeemer ISO is, compared to that in the Saucony Stabil CS3.
All in all, you can expect to get a stronger degree of pronation control from the Saucony Redeemer ISO than you would get from the Saucony Stabil CS3.
The running platform of the Saucony Redeemer ISO is also straighter than that of the Saucony Stabil CS3, thereby adding to the stability of the running shoe.
The rubber outsoles of the two running shoes differ slightly in configuration due to the difference in medial post and crash pad. However, the Saucony Redeemer ISO has a fan-shaped pattern in its forefoot that is almost like that of the Saucony Stabil CS3.
Both Saucony running shoes provide an optimal amount of separation for shock absorption and dissipation, and enough rubber to be durable running shoes.
Running shoe lab tests show that the Saucony Stabil CS3 is much more flexible than the Saucony Redeemer ISO, which turns out to be a pretty stiff running shoe.
However, stiffness is generally appreciated by heavier runners and runners who need a lot of support, which is what severe overpronators are.
The women's version of the Saucony Stabil CS3 weighs approximately 9.9 oz (281 grams) and the Saucony Redeemer ISO weighs approximately 10.7 oz (303 grams). The men's version of the Saucony Stabil CS3 weighs about 11.9 oz (337 grams), and the Saucony Redeemer ISO for men weighs 12.7 oz (360 grams).
If you need tons of stability and support, you could get that from either the Saucony Stabil CS3 or the Saucony Redeemer ISO, since both should serve severe overpronators well.
However, if you want a notch up in support and stability, as well as in cushioning, then the Saucony Redeemer ISO would be the one to consider.
And for a somewhat lighter motion control running shoe that is flexible, the Saucony Stabil CS3 would be the one to look into.
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.
