ASICS Magic Speed 5 Trainers - White/Black - Size 9 UK

The Magic Speed 5 is optimized for faster paces and shorter distances like 5k and 10k. While they can be used for marathons, especially by runners seeking a more propulsive feel, they might not offer the same level of sustained cushioning as shoes specifically designed for ultra-marathon distances.

The full-length carbon plate provides propulsion, but it's integrated into a design that aims for a less rigid and more accessible feel compared to top-tier super shoes, making it suitable for a wider range of runners and training paces.

Yes, the Magic Speed 5 can be used for daily training, particularly for faster sessions like tempo runs and intervals. However, for very long or recovery runs, you might prefer a shoe with more emphasis on plush cushioning.

A proper fit should feel snug but not constricting, with about a thumb's width of space between your longest toe and the end of the shoe. The heel should feel secure without excessive slipping.

The dual-layer midsole combines the energetic feel of FF LEAP foam closest to the foot with the stable cushioning of FF BLAST PLUS underneath. This combination aims to provide a lively, responsive, yet cushioned ride.

ASICSGRIP is a premium rubber compound known for its durability and excellent traction. It's designed to withstand the demands of regular running on various road surfaces.

Utilize the notched racing laces provided. If the issue persists, consider re-tying them with a double knot or exploring lace locks designed for running shoes.

Ensure the ASICSGRIP outsole is free from excessive mud or debris. While designed for wet conditions, extreme slipperiness can occur on highly polished or contaminated surfaces.

Confirm you have the correct size. The snug fit is intentional for performance, but if rubbing occurs, check sock compatibility and consider lacing techniques to alleviate pressure points.

The foams are designed for responsiveness. If cushioning feels significantly diminished, it may be time to consider replacing the shoes, as foam can degrade after extensive mileage.
