Which Adidas Running Shoes Offer the Best Value? A Buyer's Guide to Current Models

Adidas running shoes deliver genuine performance gains at competitive prices, but the choice between their current lineup depends on your budget and what you're training for. The Adizero Boston 13 (£114.24) leads with the latest cushioning tech, whilst the Adizero Boston 12 (£52.50) offers almost identical performance at less than half the cost, and the Ultraboost 5x (£52.00) suits everyday running and comfort-focused training.

Why Adidas?

Adidas has manufactured running footwear since 1949, building a reputation for combining German engineering precision with athlete feedback. They specialise in responsive cushioning systems—their Boost and Lightstrike foams are engineered to return energy rather than simply absorb impact, which matters on long runs where efficiency directly reduces fatigue.

What sets Adidas apart is their willingness to discount previous-generation models significantly. The Boston 12 at £52.50 shares the same Lightstrike Pro cushioning as models that sold for £130+ at launch, making it exceptional value for serious runners who don't need the latest iteration. Their Adizero line targets speed-focused training; the Ultraboost line prioritises all-day comfort and versatility.

Top Picks

Adidas Men's Adizero Boston 13w Running Shoes — £114.24

Best for runners chasing personal bests and marathon training. The Boston 13 introduces incremental refinements: a reshaped forefoot that reduces ground contact time, updated EnergyRods for propulsive toe-off, and a marginally lighter weight (around 230g per shoe). If you're logging 30+ miles weekly and racing is your focus, the marginal gains compound over months. The women's sizing (13w) indicates this is tailored for female biomechanics—narrower heel cups and a lower toe-spring than unisex models.

Adidas Adizero Boston 12 Running Shoes — £52.50

Best for budget-conscious runners who want proven speed-shoe technology without the premium. The Boston 12 retains everything that made the 11 exceptional: Lightstrike Pro cushioning (40% lighter than Boost), a carbon-infused nylon plate for energy return, and a 10.2mm heel-to-toe drop that encourages midfoot striking. For tempo runs, half-marathons, and high-mileage weeks, it's nearly identical to the 13 in real-world performance. The price drop reflects it's the outgoing model, not a quality compromise.

Adidas Ultraboost 5x Running Shoes — £52.00

Best for everyday running, cross-training, and recovery days. The Ultraboost 5x uses Boost cushioning (thicker, softer than Lightstrike) and a full-length Boost midsole that absorbs impact uniformly across the shoe—ideal for comfort over speed. The 10mm drop is more forgiving for varied terrain. At £52, it's Adidas's most versatile option: runs, casual wear, and gym sessions all work. It won't win you races, but it won't leave your feet sore either.

Quick Comparison

| Model | Price | Best For | Standout Feature | |-------|-------|----------|------------------| | Adizero Boston 13 | £114.24 | Marathon racing, speed training | Updated EnergyRods, refined toe-off geometry | | Adizero Boston 12 | £52.50 | Budget-conscious speed work | Lightstrike Pro cushioning at half the new-model price | | Ultraboost 5x | £52.00 | Everyday comfort, cross-training | Full-length Boost midsole for maximum cushioning |

What to Look For

• Cushioning type and drop: Lightstrike Pro (Boston models) suits speed and efficiency; Boost (Ultraboost) prioritises comfort. The Boston's 10.2mm drop encourages midfoot striking; the Ultraboost's 10mm drop is gentler. Choose based on whether you're racing (Boston) or training consistently (Ultraboost).
• Weight and responsiveness: The Boston 13 weighs approximately 230g and includes a carbon nylon plate for propulsion. At 270g+, the Ultraboost 5x is heavier but feels more cushioned—not slower, just different. Lighter shoes reward efficient runners; heavier shoes forgive form inconsistencies.
• Fit and sizing specifics: The Boston 13w is women's-specific with a narrower heel and adjusted arch support. Unisex or men's models will slip at the heel for many women. Measure your foot length—Adidas typically runs true to size.
• Mileage and durability: Expect 300-400 miles before noticeable compression. The Boston models, being lighter, compress faster than the Ultraboost. Buy the Boston if you're logging 20+ miles weekly; the Ultraboost if you're averaging 10-15 miles or doing mixed training.

The Bottom Line

The Adidas Adizero Boston 12 at £52.50 is the strongest all-around choice: it delivers proven speed-shoe technology at a price that undercuts most competitors, and the performance gap versus the £114 Boston 13 is marginal for anyone except elite runners. If comfort and versatility matter more than speed, the Ultraboost 5x at £52.00 matches the price and offers genuine all-day wearability. Reserve the Boston 13 only if you're seriously racing and want the latest refinements.

Frequently Asked Questions

Is Adidas good value for money compared to Nike or ASICS?

Adidas competes directly: their Boost and Lightstrike cushioning technologies match Nike's React or ASICS's Gel systems, but Adidas discounts older models aggressively—the Boston 12 at £52.50 would cost £100+ from Nike or ASICS at equivalent technology. You're getting identical performance for half the price if you don't need the absolute latest release.

What's the difference between Adizero and Ultraboost lines?

Adizero shoes (Boston, SL) are speed-focused: light weight, responsive cushioning, and a racing geometry that rewards efficient form. Ultraboost shoes prioritise everyday comfort with softer, thicker cushioning and forgiving geometry. Choose Adizero for workouts and racing; Ultraboost for daily miles and varied training.

Are Adidas running shoes good for marathon training?

Yes—the Boston 12 and 13 are explicitly built for marathon training, with Lightstrike Pro cushioning that remains responsive at mile 18 and a carbon nylon plate that reduces fatigue in the toe-off phase. The Ultraboost 5x works for marathon training if comfort is your priority over speed. Both are durable to 300+ miles, sufficient for a full training cycle.

Should I buy the Boston 13 or save money with the Boston 12?

Buy the Boston 12 unless you're racing at elite level. The 13's improvements—refined toe geometry and updated EnergyRods—shave seconds per mile for runners already below 6-minute-mile pace. For everyone else, the Boston 12 delivers 95% of the performance at 54% of the price. The real gain comes from consistent training, not the shoe generation.
