The Cambridge Dictionary defines glycerine as "a , , used in making explosives and medicines and for making . Brooks Running's 15th edition of the Glycerin is a sweet fitting and running shoe but not exactly an explosive one.
I fit true to size in the Glycerin. Plenty of forefoot volume and width with the stretch mesh upper. My mid foot is well held. Few if any will need to size up. I did not run in the Glycerin 14.
The ankle collar backs up a firm heel counter and while appearing "over-stuffed" is not. The padding all the way to the lacing is on firmer side and is key to locking in the foot given the otherwise very soft and thin mid foot overlays.
RTR review) which has a more segmented lug style outsole so is a touch less full contact and is stiffer.

The Glycerin 15 adds up to supreme comfort on the road, from top to bottom, for miles taken on the more leisurely side. It is truly a sweet and luxurious ride. While I tend to prefer a somewhat firmer more responsive ride and especially a firmer heel with thicker rubber over softer midsoles my runs in the Glycerin have been very pleasant and leg friendly. Surprisingly, I found it ran lighter than its weight and maybe even lighter than the more responsive and lighter Ghost 10. I think this largely due to its more agile and flexible forefoot.
The Glycerin 15 sets a high bar for running comfort and for many miles of durable use as a daily trainer. They are easily run sock less due to the soft, stretchy and well finished upper. Wider, higher volume feet should be happy with its toe box which as while not super wide the upper is stretchy due to the mesh and 3D Stretch Print overlays. Not exactly a speedster, it is a well executed sum of parts intended to coddle the runner but not completely disconnect from road feel. This is not a stiff, high "maximal" cushion type shoe but a well cushioned, forgiving more classic daily trainer. I wish its Super DNA midsole was a touch firmer or the drop at the heel was reduced a few millimeters to firm that part of the shoe up somewhat.
-.15 for softness of midsole, especially at heel. More outsole rubber there, a firmer midsole?
-.1 for weight, the outsole rubber is extensive
-.05 for price, superb upper aside you get most of the Glycerin in the Ghost for $20 less and Ghost is not exactly in expensive at $130,
adidas Energy Boost 2017 (RTR review) 10.9 oz $160
The Energy is 0.3 oz heavier with a similar beautiful stretch mesh upper with thin overlays but... has a fairly massive and effective plastic cage at mid foot clearly adding to weight. Its Boost midsole is competing with Brooks Super DNA here, or more likely the other way around and has higher rebound and is more energetic. There is a but... the Brooks runs nicely at slow paces if softly at the heel, the adidas not so much slow with its heavy somewhat off balance heel weight. At speed the adidas with its mid and forefoot Torsion plastic under bouncy Boost is definitely a more lively, stable and a faster shoe for me but all around heavier and heavier feeling than the Glycerin. For everyday versatility in a premium trainer and if you like soft and easy the Glycerin gets a slight nod.
Brooks Ghost 10 (RTR review) 10.4 oz $130
For $20 less the Ghost provides most of the Glycerin with 2mm more heel to toe drop by making the forefoot lower to the ground than Glycerin. Interestingl,y the toe off on the Glycerin despite the 3mm of higher stack up front was more flexible and slightly more responsive and snappy if softer too but the differences are slight. The upper is not quite the work of comfort art of the Glycerin. A touch firmer in the heel, and overall, something I prefer, the popular Ghost also given its lower cost would be my pick as a daily trainer unless I fell for that superb upper comfort of the Glycerin
Saucony Triumph ISO 3 (RTR review) 10.6 oz $150
The latest Triumph ISO is a direct competitor to the Glycerin. It's upper while comfortable and supportive does not quite have the smooth glove like fit of the Glycerin particularly at the front. Its heel is firmer than the Glycerin with snappier firmer rebound and this despite the large Everun insert embedded in a midsole that overall is firmer than Glycerin's. Transitions are not quite as smooth as Glycerin's in this stiffer shoe. Upfront while I prefer the greater flexibility and agility of the Glycerin, it is soft and not quite as stable there as Triumph. If your miles are slower and easier or you need a super comfortable recovery run shoe go with the Glycerin, if you want a more stable higher performance "big" shoe go with the Triumph.
Nike Zoom Vomero 12 (RTR review) 10.6 oz $140
The Vomero has a smoother, firmer and more consistent ride than the Glycerindue to its Zoom. Air unit upfront has a fairly stiff flex. It's upper is for sure less relaxed but great fitting. Despite the forefoot stiffness, I would give a slight nod to the Vomero for its versatility as it is more lively and responsive at speed, yet is well mannered and not overly soft at the heel at slower paces.
ASICS Gel-Nimbus 19 (RTR review) 11 oz. $160
The 0.4 oz heavier Nimbus 19 while a soft shoe like the Glycerin and for sure softer than Vomero and Triumph has an overall smoother ride than the Glycerin, particularly at the heel and at slower paces. The Nimbus absorbed shock and moved on more smoothly than the Glycerin. The firmer ASICS Flyte Foam combined with the softer Gel inserts is a superior and more responsive approach to a soft cushioned shoe. As to uppers, hands down the Glycerin's is superior. Equally supportive it is not as "suffocating" as the Nimbus, dense engineered mesh. Overall I give the nod to the Nimbus.
