# Brooks Glycerin GTS 23 Delivers Stability Without Sacrificing Cushioning
Brooks released the Glycerin GTS 23 as an update to its popular neutral daily trainer line, now with integrated stability features that maintain the shoe's trademark plush feel. The GTS designation stands for "Guidance Truss System," a technology designed to offer subtle arch support without the rigid structure found in traditional motion-control shoes.
The shoe combines DNA Tuned cushioning, a proprietary Brooks foam system, with the new guidance mechanism. Testers at Runner's World reported that the roomy fit accommodated various foot shapes comfortably. The soft cushioning layer preserved the responsive, neutral platform that made the original Glycerin popular among distance runners and daily training users.
The stability addition targets a specific problem many runners face. Not all runners need heavy-duty stability shoes, but some benefit from gentle midfoot support. The Glycerin GTS 23 bridges that gap by incorporating corrective elements that remain subtle enough to avoid the dead, heavy feeling associated with older stability designs. This approach reflects a broader industry shift toward softer, more nuanced guidance systems rather than aggressive pronation control.
Brooks positioned the shoe for versatile use across easy runs, moderate-intensity efforts, and recovery days. The roomy toe box became a standout feature for testers who typically run in neutral trainers but wanted arch support options. This fit accommodation matters because runners often avoid stability shoes due to an overly snug forefoot, which can lead to blisters and hot spots during longer distances.
The DNA Tuned cushioning responds to impact forces by adjusting firmness based on speed and body weight. At slower paces, the midsole feels plusher. At faster speeds, it provides more responsive feedback. Runners benefit from this adaptive behavior because it reduces impact stress during recovery runs while offering protection during tempo or threshold work.
The unobtrusive guidance system uses a truss-like structure embedded in the midsole to guide the foot through a more neutral motion pathway without forcing correction. Unlike older motion-control approaches that locked the foot in place, this method allows natural movement while providing nudges toward efficient alignment. This distinction matters because excessive restriction can increase injury risk by preventing the foot from adapting to terrain and running pace.
Testers consistently praised the shoe for maintaining the Glycerin line's core identity. The plush ride quality remained intact, which addressed a concern many runners have when brands add stability features. Adding support mechanisms often increases shoe weight and reduces ground feel. Brooks managed to keep the shoe responsive.
The Glycerin GTS 23 targets experienced runners seeking versatility. Someone training for a marathon might use these shoes for easy-effort days while wearing faster racing flats or tempo trainers for harder efforts. The combination of plush cushioning and subtle guidance makes the shoe suitable for runners logging high weekly mileage who want protection without sacrificing ride quality.
Pricing and availability place the Glycerin GTS 23 in the premium daily trainer category, around 160 dollars. This positions it competitively against other cushioned trainers with stability features, such as the ASICS Gel-Cumulus and New Balance Fresh Foam 1080.
The Glycerin GTS 23 represents Brooks' strategy of refining rather than reinventing successful platforms. Adding stability to an already popular shoe carries risk, but the company preserved what made the original Glycerin appealing to daily runners while addressing a genuine gap in the market for runners wanting minimal but meaningful support.
