Brooks Glycerin 23 Trainers - White - UK 4

The Glycerin 23 is available in standard width. For wider feet, it's recommended to check for specific wide (2E) or extra-wide (4E) options if available, or consult a running shoe specialist.

Most runners replace their trainers every 300-500 miles, or when they notice a significant loss in cushioning or support. This typically translates to 6-12 months of regular use.

The Glycerin 23 is designed primarily for road running. The outsole may not provide adequate grip or protection for uneven trail surfaces.

The Glycerin 23 features updated DNA LOFT v3 cushioning for enhanced softness and a renewed engineered mesh upper for improved fit and ventilation compared to older versions.

Gently brush off loose dirt. For tougher stains, use a soft cloth or brush with cool water and a mild soap. Rinse with clean water and allow to air dry completely.

The Glycerin series is known for offering neutral support, suitable for runners with a neutral gait or those who use orthotics. The cushioning system provides comfort without specific motion control features.

Adjust the lacing system for a more customized fit. Ensure you have selected the correct UK size. If the issue persists, consider trying a different size or width.

Over time, cushioning can naturally decrease. If performance feels significantly diminished, it may be time to consider replacing the shoes, typically after 300-500 miles of use.

While the outsole offers improved durability, always exercise caution on wet surfaces. The tread is designed for road running, not extreme conditions.

Ensure the shoes are properly laced and that the fit is correct. Break them in gradually with shorter runs. If discomfort persists, consult the product manual or a running specialist.
