ADIDAS Adizero RC4 - After 100 miles

Summary

In this video review, the presenter discusses the performance of the Adidas RC4 running shoe after 100 miles of use. Highlighting its durable yet responsive outsole, the midsole's firm yet slightly softened feel, and the breathable upper, the review provides insights for both casual and fast runners. The RC4 excels in short, fast workouts and interval training but isn't ideal for long distances due to its lack of cushioning. While great for a 5K race, the shoe may not be suitable for long, grueling sessions. The presenter concludes that the RC4 is a solid choice for lightweight runners seeking a responsive, minimal feel.

Takeaways

• 😀 The Adidas RC4 has a durable outsole with no major wear after 100 miles, and it should last for at least 300 miles.
• 😀 The grip on roads is acceptable, but not excellent, and the outsole doesn’t collect stones, which is a positive feature.
• 😀 The midsole features full Lightstrike foam, which is firm and responsive but lacks cushioning, making it ideal for runners who prefer a ground feel.
• 😀 After 100 miles, the midsole has softened slightly, improving comfort but still retaining its firm responsiveness.
• 😀 The torsion system in the midsole is still performing well, showing minimal signs of wear despite some scratches.
• 😀 Lightstrike foam, although initially unpopular, lasts longer and is lighter than Boost foam, maintaining its durability even after long use.
• 😀 The upper material is resistant and stylish but lacks breathability, which can lead to heat buildup during long runs, especially in warmer climates.
• 😀 The upper fabric keeps the foot securely in place with excellent lockdown, maintaining performance from day one.
• 😀 The RC4 is best suited for fast workouts and interval training, offering a responsive ride for lightweight runners but may not be the best choice for long-distance runs.
• 😀 The RC4 could be considered a daily trainer for runners who like a firm, responsive shoe and are okay with less cushioning, but it's not ideal for longer distances.

Q & A

What is the overall condition of the outsole after 100 miles of use?

The outsole is in perfect condition with no major signs of wear. Despite not being made of Continental rubber, it still offers good grip on roads and doesn’t collect stones, making it durable and reliable for at least 300 miles.

How does the midsole of the shoe perform after 100 miles?

The midsole, made from Lightstrike foam, remains firm but becomes slightly more comfortable over time. It has visible wrinkles, indicating a slight reduction in firmness, but it still offers a responsive feel. It's not the best for cushioning, but it is durable and performs well.

What are the key benefits and drawbacks of the Lightstrike foam used in the midsole?

Lightstrike foam is lighter and lasts longer than Boost foam. It offers a firm, responsive platform, ideal for runners who prefer a ground feel. However, it may not provide sufficient cushioning for those seeking more comfort during long runs.

How did the upper of the shoe perform during testing in the Canary Islands?

The upper was durable and provided great foot lockdown, but it lacked breathability compared to previous versions. This led to hotter feet during long sessions. The upper is resistant to dirt and offers a stylish overlay material that adds to the shoe's durability.

What is the recommended use of the Adidas RC4 shoes according to the reviewer?

The RC4 is recommended for fast workouts and interval training, especially for lightweight runners who prefer a responsive, ground-feel shoe. It is also suitable for short distances (up to 24 kilometers), but may not be ideal for long-distance running or races.

How does the RC4 compare to other shoes like the Boston 11 and Asics?

While the RC4 excels in speed and responsiveness, shoes like the Boston 11 and Asics provide better cushioning and support for the transition phase of a run. These shoes have more cushioning and a rocker shape in the forefoot, which improves comfort and efficiency for longer runs.

What was the reviewer’s experience running in the RC4 on a 18-kilometer session?

During the 18-kilometer run, the reviewer felt the RC4 performed well, with excellent response. However, the lack of cushioning became noticeable as the feet became hot, especially under the conditions of longer distances at faster paces.

What improvements would the reviewer suggest for the RC4 shoes?

The reviewer suggests improving the breathability of the upper, especially for warmer climates, to enhance comfort during longer sessions. Despite this, the durability and foot lockdown are praised, making it an overall solid choice.

Can the RC4 be used as a daily trainer?

The RC4 can serve as a daily trainer for lightweight runners who prefer a firm, ground-feel shoe. However, it’s not ideal for long-distance runs or those seeking extra cushioning. It works best for short to mid-distance workouts, especially interval training.

What are the durability expectations for the RC4 shoe?

The RC4 is expected to last for at least 300 miles, with no significant wear visible on the outsole and midsole. The materials used, including Lightstrike foam, are durable, offering good longevity compared to other foam types like Boost.
