How the Adidas Adizero SL 2 and Hoka Mach 6 differ
The Adidas Adizero SL 2 and the Hoka Mach 6 sit in the same speed training bucket, so the question isn't what you'd use them for — it's which one matches your stride, your weekly mileage, and your budget.
Where they actually differ: the Adidas Adizero SL 2 comes in roughly 0.1 oz lighter (7.8 oz vs 7.9 oz), which becomes noticeable on faster turnover and longer efforts; the drop differs (8mm on the Adidas Adizero SL 2, 5mm on the Hoka Mach 6) — higher-drop shoes tend to feel friendlier to heel strikers and tight calves, while lower drops favor a midfoot landing; the Hoka Mach 6 rides on the taller stack (32mm/24mm vs 35mm/30mm), giving it more under-foot cushioning at the cost of a slightly less stable platform; and the Adidas Adizero SL 2 is $10 cheaper at MSRP ($130 vs $140).
