Brooks Glycerin GTS 20 Supportive Running Shoe - Plush Support

In this review the Brooks Glycerin GTS 20 stands out as a cushioning-first shoe that adds intentional support for runners who want the softest ride without sacrificing stability. The bottom line: if you prize maximum plushness but need guidance to keep excess motion in check, this shoe delivers. It pairs Brooks' softest DNA LOFT v3 cushioning with the integrated GuideRails support system, and carries both PDAC A5500 diabetic certification and the APMA Seal of Acceptance, which makes it notable for runners who need extra comfort and proven foot health credentials.

Key Features

• Maximum cushioning: DNA LOFT v3 provides the softest, pillowy midsole feel that remains lightweight and responsive for road miles and gym use.
• Integrated support system: GuideRails gently limits excess movement to protect knees and hips while preserving natural stride mechanics.
• Certified comfort: PDAC A5500 diabetic shoe certification and the APMA Seal of Acceptance indicate attention to foot health and comfort for sensitive users.
• Smooth transitions: Redesigned outsole geometry and updated cushioning combine for steadier, more stable toe-to-heel roll.
• Versatile use: Built for road running but equally suited to cross training and everyday wear where cushioning and support are priorities.

Who It's For

The Glycerin GTS 20 is best for runners and active users who believe more cushioning is better and who also need additional midfoot and knee support. It suits neutral to mild overpronators who want plush daily trainers for long runs, recovery days, gym sessions, or walking while minimizing impact on the knees.

Runners seeking a minimal, firm, or race-focused shoe should look elsewhere; this model emphasizes softness and support over lightweight speed. Also, those who prefer a very narrow, performance racing fit may find the recommended half to full size up guidance necessary for a comfortable fit.

Pros & Cons

Pros

• Exceptionally soft and comfortable midsole that cushions long miles and recovery runs.
• GuideRails support helps reduce excess motion and offers protection for knees and hips.
• Health-focused certifications (PDAC A5500 and APMA Seal) reassure users with sensitive feet.

Cons

• Maximal cushioning adds weight and a slower, less race-oriented feel compared with speed-focused shoes.
• Fit guidance recommends ordering a half to one size larger than dress shoes, which may surprise buyers used to true-to-size fits.
