adidas Supernova Trainers - Grey - 9.5 UK

Yes, the Supernova series is designed for long-distance training and comfort, making them a viable option for marathon preparation.

While primarily a running shoe, they are stable enough for light gym work, though specialized weightlifting shoes are recommended for heavy lifting.

No, the mesh is designed for breathability. They will get wet in heavy rain or puddles.

Use a specialized sneaker cleaner or a mild soap solution and a soft cloth, wiping carefully to avoid staining the grey fabric.

Refer to the adidas sizing chart and ensure there is roughly a thumb's width of space between your longest toe and the front of the shoe.

Gently scrub with a soft brush and a mixture of water and mild detergent; air dry thoroughly.

Re-lace the shoes using a 'runner's loop' or heel lock lacing technique to secure the ankle.

This is a sign of material wear; if you have surpassed 400-500 miles, it may be time to replace the footwear.
