No improvements over the ST-2 but a change for the worse


I am a big fan of the ST-2 and so a little bit disappointed of the ST-3.
At my size (US 10) it's almost 10% heavier. The new upper sucks quicker and more water when it rains. Also the distribution of forces feels uneven due to the small side lashes. The whole upper feels more insecure to me and is getting dirty much faster.
As a successor it lacks real improvements, for example a more durable insole.
Please bring the ST-4 as quickly as possible, thank you. :)

The ST-3 is a great long haul zero drop option.


If you liked the ST-2, you’ll probably like the ST-3. They feel super similar, but with the addition of the plusher midsole makes it feel a little more cushioned. Standing and walking in them reminded me of a very popular competitor model, but running still had the same zero drop, ST-2 feel. And know I’ll be able to spend a lot of time in them without any issues. The new upper feels great. They don’t feel too restrictive with the socklike material, but also, not too loose. The heel is still collapsible, but feels like a slightly “beefed up” neoprene. The lacing felt just right. They are super light, and very breathable. All in all, super happy with the update. I really like the new color way.

I am a Topo Athletic Ambassador, but have been a huge fan of the ST series since day one.

Firm cushion, travel friendly but not much structure


I never had the ST-2, but I have the Magnifly2 and ST-3. The cushion is firmer than the Magnifly2 but the ST-3 shoe is much more flimsy. My foot did not feel secure in the shoe and was not confident doing a gym workout in them.
ST-3 is definetely very breathable and travel friendly, but there's not much structure.
I would use this more like a water shoe and take it when i do water sports.
