adidas Ultraboost 1.0 - Black - UK 5.5

Yes, the adidas Ultraboost 1.0 is well-suited for regular running training, including longer distances, thanks to its responsive BOOST midsole and comfortable PRIMEKNIT upper. It provides excellent cushioning and energy return for a smooth ride.

The Ultraboost 1.0 generally fits true to size. We recommend trying them on to ensure the best fit, especially considering the sock-like feel of the PRIMEKNIT upper. Your usual adidas size for trainers should be a good starting point.

While primarily a running shoe, the Ultraboost 1.0's stability, comfort, and Continental Rubber outsole provide good versatility for various gym activities, including light weightlifting, cardio machines, and general fitness classes. For highly specialized cross-training or heavy lifting, a shoe designed specifically for those activities might be more appropriate.

The BOOST midsole is made from thousands of thermoplastic polyurethane (TPU) pellets, fused together to create a material that is incredibly soft, bouncy, and durable. It provides superior cushioning and energy return, meaning more energy comes back to you with every step, making runs feel easier and more comfortable.

Parley Ocean Plastic is upcycled plastic waste intercepted from remote islands, beaches, coastal communities, and shorelines, preventing it from polluting our oceans. By incorporating this into the PRIMEKNIT upper, adidas is actively contributing to reducing plastic waste in marine environments.

The frequency of cleaning depends on your usage. For regular wear, a quick wipe-down of the upper and sole after each use can prevent dirt buildup. For more intensive use or visible dirt, a thorough cleaning as described in the 'Care Instructions' section is recommended every few weeks or as needed.

Adjust the lace closure. Ensure laces are evenly tensioned across your foot. Experiment with different lacing patterns if standard lacing doesn't provide the desired fit. For a wider foot, you might try skipping the bottom eyelets. For a tighter fit, try a runner's loop.

Check the Continental Rubber outsole for accumulated dirt, mud, or debris. Clean the outsole thoroughly with a stiff brush and water to restore maximum traction. Ensure the tread isn't excessively worn, which can reduce grip over time.

This can happen with knit materials from rubbing. Carefully trim any loose threads with small, sharp scissors. Avoid pulling snags, as this can worsen the issue. For general fuzziness, a fabric shaver designed for delicate materials can be used sparingly.

While the PRIMEKNIT upper offers breathability, individual comfort levels vary. Try wearing moisture-wicking athletic socks to help manage sweat. Ensure your shoes are not laced excessively tight, restricting airflow. Allow shoes to air out between uses.
