Brooks Glycerin 19                                                   Brooks Glycerin 19 GTS

The updated Brooks Glycerin now has two versions: the regular, plush-cushioned neutral daily trainer, as well as the GTS model that provides subtle stability through the use of Brooks’ GuideRails technology. For those of you previously running in the Transcend, the Brooks Glycerin 19 GTS is your new shoe: plush cushioning with stability. Both versions of the updated Glycerin feel the same under foot. The stack height of the shoe has increased several millimeters, but the drop has changed to 8 mm, due to a greater increase of midsole material under the forefoot. The result of this rejiggering and utilization of more DNA Loft foam is a shoe that is even softer than before. This is an ideal daily trainer for runners putting in some higher mileage weeks, or runners who are spending some time on sidewalks. The upper of the updated Glycerin receives some additional volume and can accommodate a greater variety of foot shapes. Brooks’ 3D Fit Print keeps everything secure without any obtrusive overlays. For those who need some heel security, the Glycerin has a solid, stiff heel counter. The new GTS version of the Glycerin uses GuideRails to provide subtle stability. The medial rail is slightly firmer and is more noticeable at slower paces. This would be great shoe for those long runs where running form tends to deteriorate in the latter miles. The GuideRails will keep your form dialed in as you get tired. Overall, Brooks’ idea to make a stability version of the Glycerin to replace the Transcend was a good one. The only question you need to answer — come in and try them out! — is which version is best for you.
