Allbirds Wool Runner GO Review 2025: Improved Structure and Support

The Allbirds Wool Runner GO is a welcome update to the original wool runners for three main reasons discussed in my video above. 

1. More structure than the originals! You can see in my video how the merino wool upper is thicker and sturdier than the originals which means the shoe keeps its shape after wear. No more sloppy fit.
   
2. The SweetFoam® midsole is thicker and sturdier. I always found my heels and ball-of-foot area sunk into the original midsole leading to plantar fasciitis pain. My feet feel better supported in the Allbirds Wool Runner Go sneakers. This is also good news for feet that suffer from hallux limitus or hallux rigidus (big toe arthritis). The shoe doesn’t bend as much at the forefoot, protecting the big toe.
   
3. Half sizes = better fit. There’s even a unicorn women’s 10.5!

My biggest concern about the updated Allbirds Wool Runner Go is not so much the width of the toe box, rather the height. It seems shallower. This could be good news if you have a low volume foot, but you may find the shoe feels tight across the top initially. I’m fairly certain the wool will stretch out with time, but that’s my initial take.

The women’s Allbirds Wool Runner Go is available in whole and half sizes 5-11 for $55 men’s version in whole and half sizes 8-14 for $55 from Allbirds
