My toes are short and stubby, and I was finding that the toes on my new Ininjis were way too long--leaving a bunch of sock sticking out beyond my toes! So here's what I have found works.
I put my foot in the sock with my toes just barely poking into the toe holes. Then I grab the base of one of the Ininji's toes (with the thumbs and forefingers of both hands) and carefully pull it over my toe. That way it's not stretching out as I put it on. Repeat with every other toe. They fit so much better now!
For all I know, this is totally obvious to everyone else, but it took me a few times to figure it out.
