...Typically the longest (second) toe is affected but it can be all of them (!),
A bit of a tangent - am no expert on feet, but am always a bit startled to see feet where the great toe isn't the longest as it is in my family.
Second toe is often longer. There are many links, here are 2 that I just Googled up
Hallux Podiatrist Whenever examining feet/toe shape or anatomy, Xrays, boot fitting, etc, the actual anatomy is best learned with weight-bearing, ie, standing up.
And for what I hope is a photoshopped image:
