Brooks Glycerin 13 delivers a soft ride with a smooth heel-to-toe transition to neutral runners. Saucony Triumph ISO 2 offers cushiness and a secure fit at a lighter weight.
The Brooks Glycerin 13 and the Saucony Triumph ISO 2 are neutral running shoes that are very cushy and can be worn by heavier runners who do not need any kind of stability and support.
The Brooks Glycerin 13 and the Saucony Triumph ISO 2 look very much alike in the way they are constructed and what they have got to offer.
Starting with the upper, both the Brooks Glycerin 13 and the Saucony Triumph ISO 2 have broad overlays wrapping the midfoot.
While these overlays are mostly no-sew, they do contain some stitches at the beginning and end to keep the overlays in place.
The overlays wrapping the midfoot are located far enough backwards to really open up the toe box for comfort. Their position and form are more favorable in the Brooks Glycerin 13 than they are in the Saucony Triumph ISO 2, though.
While the toe box is mostly overlay-free in the Saucony Triumph ISO 2, except for a welded-on piece at the front, the toe box of the Brooks Glycerin 13 has 3D Fit Print overlays running over the toe box and everywhere else in the upper to give it more structure and support.
Another difference is that the Saucony Triumph ISO 2 has an external support frame that cups the heel well. The Brooks Glycerin 13 does not have such a support frame. However, you should still get enough support at the back of the Brooks Glycerin 13.
Similarities between the two running shoes continue in the midsole where both the Brooks Glycerin 13 and the Saucony Triumph ISO 2 provide heel-to-toe cushioning.
The Brooks Glycerin 13 implements premium midsole cushioning through Super DNA while the Saucony Triumph ISO 2 has an EVERUN topsole and misole construction.
The Saucony Triumph ISO 2 has a layer of soft cushioning right under the sockliner, to give you a nice bouncy feel.
Running shoe lab tests show that the Saucony Triumph ISO 2 is overall more cushy than the Brooks Glycerin 13 in both the heel and the forefoot, and for both men and women.
The difference in cushioning between the two running shoes is noticeable in lab tests with the Saucony Triumph ISO 2 being perhaps about 10 – 20% more cushy.
Lots of cushioning has the positive effect that a running shoe may feel soft under your foot, but it also has the negative effect that it could make a shoe stiff, especially if the midsole is thick.
Running shoe lab tests show that both the Brooks Glycerin 13 and the Saucony Triumph ISO 2 are quite stiff for women, but that the Brooks Glycerin 13 is super flexible compared to the Saucony Triumph ISO 2 for men.
The latter may also have to do with the layout of the outsole of the Brooks Glycerin 13.
While both running shoes provide full ground contact, which benefits stability and smoothness of transition, the Brooks Glycerin 13 has three separate zones to distribute pressure, but the separation and flex grooves between these zones may also help with flexibility.
While the Saucony Triumph ISO 2 has flex grooves running from side to side, they are not as straight as those in the Brooks Glycerin 13 and the separation between the midfoot and rearfoot is not as clear as in the Brooks Glycerin 13.
The women's version of the Saucony Triumph ISO 2 weighs approximately 8.6 oz (244 grams), while the Brooks Glycerin 13 for women weighs approximately 8.9 oz (252 grams).
The men's version of the Saucony Triumph ISO 2 weighs about 10.4 oz (295 grams), and the Brooks Glycerin 13 for men weighs about 11.0 oz (312 grams).
If you are looking for a plush ride and secure fit from a neutral running shoe, you could get both from either the Brooks Glycerin 13 or the Saucony Triumph ISO 2.
However, if you are looking for a somewhat lighter running shoe, the Saucony Triumph ISO 2 may suit you better than the Brooks Glycerin 13. And for flexibility, men would be better off going with the Brooks Glycerin 13 than the Saucony Triumph ISO 2.
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.
