Adidas Adizero Adios Pro 4 Review After 100 Miles

Introduction

The Adidas Adizero Adios Pro 4 is the fourth iteration of Adidas’s super racing shoe, and this version moves in a noticeably more aggressive direction than its predecessor. The previous version was a more versatile option that suited a wide range of runners; this one is built with faster runners firmly in mind.

Most impressions of new racing shoes come from the first 20 to 40 miles, so it is worth looking at what happens well beyond that point. After 100 miles, the story changes: the initial snap fades, the cushioning softens, and the shoe settles into a different character. That evolution matters when you are deciding where to spend your money.

At size 9, the men’s version weighs 7.1 oz (201 g), and a women’s size 8 comes in at about 6.4 oz (181 g). The stack measures 39 mm in the heel and 33 mm in the forefoot for a 6 mm drop, sitting close to the World Athletics limit.

Who This Product Is For

This is a shoe for faster runners. The ride is now genuinely on par with the most aggressive options on the market, and in the early miles it delivers a bouncy, resilient feel that makes 5K and 10K paces accessible in a way the previous version never quite managed.

If you are not especially fast, think carefully before buying. The aggressive geometry and narrow heel and midfoot demand stable mechanics. Runners who land on their forefoot will thrive here; heel and midfoot strikers will feel a wobbly rearfoot, especially as the soft foam breaks in, and the shoe becomes fatiguing beyond roughly 13 to 14 miles for anyone without stable neutral mechanics.

Main Strengths

Durability is the headline. At 102 miles, the outsole is barely worn, with no wear-through at all. That is exceptional for a super shoe, most of which show meaningful wear well before this point. If outsole longevity is a priority, this shoe genuinely delivers on miles per dollar.

The midsole is a newer, softer mix of Lightstrike Pro that was remarkably resilient and bouncy out of the box, and the softness and compliance have stuck around throughout the mileage. Long uptempo runs feel great underfoot, and the quick toe-off rollover rewards runners who land farther forward.

The fit is another strong point. The upper is light and snug, with just enough forefoot room and a secure, locked-in midfoot and heel. There is no stiff heel counter, which makes this an excellent choice for runners with sensitive heels or Haglund’s deformity, and it still holds the foot firmly. No lace-locking tricks were needed to keep the fit secure.

Things to Consider Before Buying

The biggest change over 100 miles is the loss of that sharp, snappy feel. The quick rebound that made short 5K and 10K efforts so much fun faded somewhere around 50 to 60 miles. What remains is a softer, more compliant ride that now suits tempo runs and longer efforts better than short speedwork.

The rearfoot also gets wobblier as the foam softens. Early on, the heel felt stable; after extended mileage, the narrow heel and midfoot combined with the softened foam create a noticeable lateral bias that pushes the foot outward. Runners who land farther back need stable, neutral mechanics to enjoy this shoe.

Sizing deserves real attention. This shoe fits about a quarter to a half size short, and it does not loosen up over time. The toe guard creates pressure at the front of the foot, and repeated long runs in a true-to-size pair can leave a bruised toe. For 5K and 10K use, your normal size works well. For half or full marathon distances, going up half a size is strongly recommended.

Buying Advice

At $250, this is a premium shoe, and the value case rests on its durability and early bounce. The previous version managed to reach 100 miles only barely; this one arrives at 100 miles with plenty of life left in it. If you want a super shoe that hangs on for the long haul, the Pro 4 earns its price.

If you want something more versatile across a variety of paces, the previous version will likely be discounted and remains the better all-rounder. But if your focus is marathon efforts, tempo runs, and longer races, and you can live with the midsole softening and the loss of short-distance snap, the Adios Pro 4 is a strong investment.

Conclusion

After 100 miles, the Adizero Adios Pro 4 reveals itself as a shoe of two phases: an aggressive, snappy racer early on that matures into a soft, comfortable long-distance option with outstanding outsole durability. Forefoot strikers with stable mechanics and an eye on longer races will get the most out of it. Size up half a size for anything beyond 10K, and know that the sharpest feel you get in the first miles is not the shoe you will be wearing at mile 60.
