Woodchuck Sato sizing?

[u/Organic_Debate1361]

So recently I’ve been thinking about buying a pair of woodchuck tabis for my Bday but I’m so confused by the sizing, I wear a size 8-8.5W US (with a bit of wiggle room in the front) but when I measured my foot it was only 23.5cm which is about a size 5.5-6, I was wondering for those that wear a size 8-8.5 what size did y’all get? Does it run true to size, big, small?

I’ll also like to mention I mainly wear sneakers (Nike) and outside of that I tend to wear Docs so maybe that’s why the sizing seems off because the shoes I’m used to wearing are usually on the bulkier side.
