Under Armour UA Assert 11 - Black - Trainers - UK 11.5

The Assert 11 is designed for general training and comfort. While suitable for shorter runs, they may not offer the specialized support and cushioning required for marathon distances. For marathon training, consider a shoe specifically designed for long-distance running.

The Assert 11 is designed as a 'Neutral' shoe, meaning it provides a balance of flexibility and cushioning without specific pronation control. If you have a neutral foot strike, these should be a good fit. If you overpronate or supinate significantly, you might need a shoe with more targeted support.

The athletic mesh upper can be breathable but is not waterproof. While the rubber outsole provides traction, they are not designed for heavy rain or wet environments and may not keep your feet dry.

The soft, antimicrobial sockliner helps to keep your feet comfortable and prevents the buildup of odor-causing bacteria, contributing to a more hygienic and irritation-free experience.

The upper of the Under Armour Assert 11 trainers contains at least 30% recycled content, reflecting a commitment to sustainability.

The Assert 11 is positioned as a versatile trainer offering a good blend of comfort and durability for general use. More specialized running shoes from Under Armour might offer advanced features like enhanced energy return, specific stability elements for different pronation types, or lighter weight for competitive racing.

This can sometimes occur with new shoes. Try wearing them for a few more sessions. If it persists, check if moisture has entered the shoe or if there's an issue with the insole.

Ensure the size is correct and laces are adjusted properly. Break in the shoes gradually with shorter wear times initially. The antimicrobial sockliner should help reduce irritation.

Ensure the rubber outsole is clean from debris. If the shoes are significantly worn, the tread may need replacing, or you may need to consider a different shoe model for highly specific grip requirements.
