The offset is 8mm, with 36mm in the heel and 28mm in the forefoot.

The shoe weighs 8.4oz (238g).

While comfortable, their design is optimized for performance. For daily wear, consider if the firm, performance-oriented feel is what you desire.

Clean with a damp cloth and mild soap, then air dry away from direct heat. Avoid machine washing.

Ensure you have selected the correct size. Try wearing thinner running socks. If the issue persists, the shoe's fit may not be suitable for your foot shape.

The cushioning and plate may naturally lose some of their snap after extensive mileage. Ensure the shoes are clean and free from debris that might affect performance. Regular cleaning and proper drying can help maintain their condition.

While the outsole provides good coverage, ensure the running surface is not excessively wet or slippery. The shoe's grip is optimized for dry to moderately wet conditions.
