Adidas Adizero Adios Pro 2 vs. Saucony Endorphin Pro 2 (2021)

Both carbon plate shoes have a high stack (max cushioning) and weigh about the same (less than 8.1 oz/230 g for the men’s version).

The main difference is in the carbon plate configuration: it’s in one piece on the Endorphin Pro 2 but six parts on the Adios Pro 2 (including five rods under the forefoot).

The result is more explosive cushioning on the Endorphin Pro but more versatility on the Adios Pro 2. Thus, the Endorphin Pro seems more appropriate for pure speed, while the Adidas also lends itself well to slower paces. It’s even more the case on the second version released in 2021.

Also, the Endorphin Pro 2’s cushioning is firmer than the Adios Pro 2’s, which may not be comfortable for everyone. So if you prefer soft cushioning, the Adios Pro might be a better choice for longer distances.

In terms of stability, the Endorphin Pro seems to have a slight advantage even though Adidas features a wider platform on the second iteration of their elite shoes.

Finally, versions 2 (2021) of these shoes both offer a good foot lockdown even if, as always, some runners complain of minor problems here and there. It’s particularly the case with the Adios Pro, which can run a little large in length.

Endorphin Pro vs Adios Pro: which one to choose?

According to our review analysis, the consensus is that the Saucony Endorphin Pro 2 is more suitable for short and medium sessions (ideally 5-10k). At the same time, the Adios Pro is more comfortable on long distances overall, including the half marathon.

However, it’s a personal question. If you like shoes with firm cushioning, then you should love the Endorphin Pro 2, even on longer distances like the marathon.
