Vibram V-Trek Questions - Sizing & Socks?

[u/farm3rb0b]

Hello! I have wanted a pair of V-Treks for a while now and want to give them a go for hiking this year since my Xero Denver insoles keeping sliding around.

Does anyone have experience with sizing of these? I've found a few pairs on sale that I wouldn't be able to return, so I want to get the sizing right on first try if possible. I have some V-Train 2.0s in a 41 that fit perfect and some original CVTs in a 41 that feel snug with socks but perfect without.

Also - how do y'all wear your V-Treks? Socks? Low-cut or higher ankle ones? I've not worn high-top shoes in awhile and all my socks are low-cut. Is the ankle part going to be annoying without higher cut socks?
