BOSS Bulton Runn Trainers - Black - Size UK 11

The upper material is 100% cow skin (polished leather), the lining is 100% polyester, the innersole is 100% goat leather, and the sole is 100% rubber.

These trainers are proudly made in Portugal, ensuring high-quality craftsmanship and production standards.

Wipe the leather with a soft, damp cloth after each use. Periodically apply a leather conditioner and a suitable shoe polish (neutral or black) to maintain its shine and protect the material from drying out.

While they are 'trainers,' their polished leather design makes them more suitable for smart-casual, daily wear, and urban exploration rather than strenuous sports or running activities, which could damage the leather.

These trainers are true to UK size 11 for adult males. We recommend trying them on to ensure a comfortable fit, allowing for minor break-in as the leather and innersole conform to your foot over the first few wears.

Yes, the laces are fully replaceable. You can use any standard trainer laces that match the original length and width to refresh their look or suit your personal preference.

Clean the leather with a soft, damp cloth, then apply a suitable leather conditioner followed by a neutral or black shoe polish to restore shine and cover minor scuffs.

Wear them for short periods around the house to gradually break in the leather and innersole. The goat leather innersole will conform to your foot over time, improving comfort.

Ensure you are using a secure knot, such as a double knot. You may also consider replacing the laces with a slightly different material or texture if the issue persists.

Allow trainers to air out thoroughly after each wear. Use shoe deodorizers or sprinkle baking soda inside when not in use. Ensure you wear appropriate moisture-wicking socks to help absorb perspiration.

While normal wear is expected, excessive wear might indicate a need for professional resoling. For minor loss of grip, ensure the sole is regularly cleaned to remove embedded dirt and debris.
