You're question makes no logical sense. Of course they aren't always innocent, if one person in the world ever gave a foot massage which was innocent then the answer is no??
And still, of course they aren't. Doesn't mean they're always not innocent either though...
oh dear... you're in trouble XD

Ok,
How about when they have a boyfriend? Also removing her socks..
Jules: Whoa, whoa, whoa, whoa... stop right there. Eatin' a ***** out, and givin' a **** a foot massage ain't even the same ****in' thing.
Vincent: It's not. It's the same ballpark.
Jules: Ain't no ****in' ballpark neither. Now look, maybe your method of massage differs from mine, but, you know, touchin' his wife's feet, and stickin' your tongue in her Holiest of Holies, ain't the same ****in' ballpark, it ain't the same league, it ain't even the same ****in' sport. Look, foot massages don't mean ****.
Vincent: Have you ever given a foot massage?
Jules: [scoffs] Don't be tellin' me about foot massages. I'm the foot ****in' master.
Vincent: Given a lot of 'em?
Jules: **** yeah. I got my technique down and everything, I don't be ticklin' or nothin'.
Vincent: Would you give a guy a foot massage?
[Jules gives Vincent a long look, realizing he's been set up]
Jules: **** you.
Vincent: You give them a lot?
Jules: **** you.
Vincent: You know, I'm getting kinda tired. I could use a foot massage myself.
Jules: Man, you best back off, I'm gittin' a little ****** here.

I once gave a foot massage to a female friend, she had split from her boyfriend and was feeling down. I went round for a drink and a chat and somehow it got onto the subject of a crappy massage course i had done at a night school thing years ago.
She said she had never had a foot massage would i do a quick one on her so she could see what it was like.
Needless to say we had consumed a fair bit of alcohol so the "quick" massge lasted about 35mins! she was VERY relaxed at the end and also by her own admission somewhat aroused
Nothing happened as we didnt really think of each other that way, never had, but the fact that the massage had her feeling randy rather suggests that they can be far from innocent.
Hang on, I thought this was spam but now it's sounding increasingly more interesting.
Well she is in my spare room for a few weeks, I am doing a favour for her sister by letter her stay. This was after watching The Lion King at 2am, and a couple of glasses of wine.
Interesting. I can't comment on whether she is attracted to me or not. She has said though that I have a nice smile and nice teeth.
So it can get the aroused, good job. I'll have to say to her one evening that I didn't get the chance to finish it because we were interupted.
