How the Adidas Adizero Adios Pro 4 and Saucony Endorphin Pro 5 differ
The Adidas Adizero Adios Pro 4 and the Saucony Endorphin Pro 5 sit in the same racing 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 Adios Pro 4 comes in roughly 0.2 oz lighter (7.1 oz vs 7.3 oz), which becomes noticeable on faster turnover and longer efforts; the drop differs (6mm on the Adidas Adizero Adios Pro 4, 8mm on the Saucony Endorphin Pro 5) — higher-drop shoes tend to feel friendlier to heel strikers and tight calves, while lower drops favor a midfoot landing; the Saucony Endorphin Pro 5 rides on the taller stack (32mm/26mm vs 39.5mm/31.5mm), giving it more under-foot cushioning at the cost of a slightly less stable platform; and the Saucony Endorphin Pro 5 is $75 cheaper at MSRP ($300 vs $225).
