Bottom line

Brooks markets the Glycerin 14 as one of its flagship neutral and ultra-cushioned shoes. Although it does not match the truly max cushioned shoes of other brands, it does have a near pillowy cushioning and is substantially lighter than many of the competition. It offers excellent arch support, very supportive, and continues to deliver a flexible ride that belies the amount of cushioning. The shoe is quite light for 10Ks to mid-distance runs at moderate speed and packs enough cushioning for those who love to pile on the miles.

User reviews:

  • The Brooks Glycerin 14 is almost an exact replica of the previous model. Only the slightest tweaks in the upper and outsole give it an improved performance and fit over the earlier version.
  • In the latest instalment of the Glycerin the seamless 3D stretch upper. Some of the thick overlays near the back end of the midfoot saddle have been replaced with printed overlays to reduce weight and enhance breathability. The forefoot 3D overlays have also been re-aligned to give more structure to the mesh.
  • In the outsole of this Brooks shoe, the flex grooves are a bit deeper while there are more carvings on the rubber pods. These are designed to improve flexibility and traction in the shoe.

The fit of the 14th iteration of the Glycerin is very identical to the prior edition, except for the more sock-like fit in this version. There is an improved wraparound feel all over the foot provided by this shoe. The heel and midfoot have adequate hold with enough room in the toe box for mid-run swelling. It runs true to size.


The outsole of the Brooks Glycerin 14 is a maze of rubber pods and flex grooves. Brooks strategically places the rubber pods to act as Ideal Pressure Zones to help attenuate shock and make the ride a bit smoother. The flexibility is also improved with this design. A tough carbon rubber is placed in the heel and the usual areas prone to wear and tear while blown rubber covers most of the underfoot for better traction.


Brooks uses a proprietary Super DNA midsole that provides the cushioning needs of the runner 20% better than the original BioMoGo DNA. It is very light and responsive as well. Because it covers the entire length of the midsole, there is also an enhanced transition in the gait cycle with this design. Like the outsole, the midsole is also filled with grooves to boost the shoe’s flexibility. For a very highly-cushioned shoe, the flexibility gives it a smoother and nimbler feel.


The upper is basically an open mesh with very few 3D overlays. It is very breathable because of the large holes in the mesh. It is as breathable as the Brooks Glycerin 16.

A midfoot saddle that directly connects to the laces keep the foot secure and adds support to the upper. The tongue and the collar are well-padded for excellent next to skin feel. A soft sockliner adds cushioning and support in the Brooks Glycerin 14.
