Should I choose Boston 12 or Adios Pro 4?

Verdict: Choose the adidas Adizero Boston 12 first as a versatile, cost-effective daily trainer that handles everyday miles and tempo workouts, reserving the adidas Adizero Adios Pro 4 for specialized race-day competition when seeking peak marathon performance.

Choose the adidas Adizero Boston 12 for high-mileage training durability and versatile workouts, but select the adidas Adizero Adios Pro 4 for peak race-day performance and maximum energy return.

The choice comes down to daily training durability versus specialized race-day performance. The adidas Adizero Boston 12 is priced at $160 and features a hybrid midsole of Lightstrike Pro and firmer Lightstrike 2.0 with glass-fiber EnergyRods 2.0, robust Continental rubber (tested at just 0.7 mm of abrasion wear), an accommodating 73.2 mm big toe width, and maximum 5/5 breathability, balancing everyday longevity against a 9.1–9.4 oz (260–267 g) weight. Conversely, the $250 adidas Adizero Adios Pro 4 is an elite 7.1 oz (201 g) super shoe that sheds approximately 2 oz by utilizing a 100% full-length Lightstrike Pro midsole, carbon-infused EnergyRods 2.0, and an ultra-thin 1.0 mm outsole layer (with 2/5 breathability) engineered specifically to maximize energy return and running economy on race day.

Best for Boston 12

  • High-mileage daily training and uptempo workout sessions
  • Runners seeking high outsole longevity with only 0.7 mm lab abrasion wear
  • Maximum upper ventilation (lab breathability score of 5/5)
  • Runners needing a more accommodating forefoot fit (73.2 mm big toe width)
  • Budget-conscious athletes wanting a versatile performance shoe at $160

Best for Adios Pro 4

  • Peak half-marathon and marathon road race-day competition
  • Maximum running economy via an ultralight 7.1 oz (201 g) profile
  • Top-tier energy return from a 100% Lightstrike Pro foam midsole
  • High-speed propulsion through full-length carbon-infused EnergyRods 2.0
  • Snug, high-speed lockdown via the race-tuned Lightlock woven upper

When not to compare directly

Do not compare them directly when seeking a pure high-mileage workhorse or a dedicated racing super shoe, because the adidas Adizero Boston 12 is engineered for daily training durability and breathability, whereas the adidas Adizero Adios Pro 4 is built specifically as an ultra-lightweight, race-day marathon super shoe.

What are the key differences between Boston 12 and Adios Pro 4?

  • Midsole Foam & Rod Construction

    While the adidas Adizero Boston 12 pairs a hybrid dual-foam setup of Lightstrike Pro and Lightstrike 2.0 with flexible glass-fiber EnergyRods 2.0, the adidas Adizero Adios Pro 4 uses 100% premium Lightstrike Pro foam with full carbon-infused EnergyRods 2.0 for maximum energy return.

    Boston 12: The adidas Adizero Boston 12 combines a top layer of bouncy Lightstrike Pro foam with a firmer bottom carrier of Lightstrike 2.0 EVA foam, sandwiching flexible glass-fiber EnergyRods 2.0 to balance daily training durability with responsive forefoot propulsion.

    Adios Pro 4: The adidas Adizero Adios Pro 4 utilizes a 100% dual-layer Lightstrike Pro supercritical foam midsole paired with full-length carbon-infused EnergyRods 2.0, maximizing energy return and high-speed race responsiveness without any standard EVA carrier foam.

    Scores — Boston 12: 7.5/10, Adios Pro 4: 9.5/10

    Midsole composition and rod materials dictate the shoe's energy return, responsiveness, and underfoot firmness.

    The Adidas Adizero Adios Pro 4 weighs around 7.1 oz (201 g), making it roughly 2 oz lighter than the Adidas Adizero Boston 12 at 9.1–9.4 oz (260–267 g) for superior running economy.

  • Outsole Durability & Lifespan

    The Adidas Adizero Boston 12 offers superior outsole lifespan for daily training due to extensive Continental rubber suffering only 0.7 mm of lab abrasion wear, whereas the Adidas Adizero Adios Pro 4 reduces longevity with a minimalist 1.0 mm thick layer designed strictly for race-day weight savings.

    Boston 12: The adidas Adizero Boston 12 features a lightweight engineered mesh upper that provides a wide, accommodating forefoot (73.2 mm big toe width) and scored a perfect 5/5 in lab breathability smoke tests [1]. However, its upper construction requires careful lacing adjustments around the thin tongue and midfoot to achieve a secure lockdown [1, 7].

    Adios Pro 4: The adidas Adizero Adios Pro 4 utilizes a race-tuned Lightlock woven upper paired with a gusseted tongue and internal support bands for a secure, high-speed lockdown, but it features a narrow, tapered toebox and low lab breathability scoring just 2/5 [2, 10].

    Scores — Boston 12: 8/10, Adios Pro 4: 6.5/10
