Brooks Glycerin 23 Trainers - Black/Grey

The Glycerin 23 features the updated DNA LOFT v3 cushioning for an even softer feel and a renewed engineered mesh upper for improved breathability and a more secure fit.

The Glycerin 23 is available in standard width. For individuals needing a wider fit, it is recommended to check for availability of wide (2E) or extra-wide (4E) options, though these may not be listed for every colorway or size.

A UK size 13 should allow about a thumb's width of space between your longest toe and the end of the shoe when standing. Ensure there's enough room to wiggle your toes without feeling cramped.

While comfortable, the Glycerin 23 is primarily designed for running. For gym workouts involving lateral movements or heavy lifting, dedicated cross-training shoes are recommended for better stability and support.

The lifespan typically ranges from 300 to 500 miles, depending on running surface, body weight, and running form. Regular inspection for wear on the outsole and midsole compression is advised.

Use a soft brush or cloth with cool water and mild soap. Gently scrub the mesh and rinse with clean water. Always air dry.

The significant cushioning and support offered by the Glycerin 23 can be beneficial for individuals with plantar fasciitis, as it helps to absorb impact and reduce strain on the foot. However, individual results may vary.

The engineered mesh upper is designed to stretch and adapt. Wear them for short periods initially, or consider using slightly thinner socks if the fit is snug.

Ensure you are running on appropriate surfaces (roads, light trails) and that your gait is neutral. Significant uneven wear could indicate a need for gait analysis.

While DNA LOFT v3 is durable, cushioning can decrease with extensive mileage. Consider replacing the shoes after approximately 300-500 miles, or when you notice a significant reduction in comfort.
