Here is just that, a simple list of the shoes I would recommend looking into:
Skora Phase (really ANY Skora shoe would be great)
inov-8 Bare-XF 210
inov-8 Bare-XF 260
Altra The One
New Balance Minimus Zero
New Balance MT00 Minimus
"Hey, what about X, Y, Z shoe!?"
There are a lot of other shoes for Crossfit that Look really good, but they violate my one hard-line rule of Zero drop only.
