As the Amazing Hetero Man, I've always had the super power to find sexy ladies sexy. It's my gift; it's my curse.
Samus was always intriguing in that after a long and arduous battle where she'd won the day via strength, skill, strategy, technology, speed, accuracy, intelligence, and any other virtues she has, she'd be like, "Oh, by the way, I'm sexy as all hell. Didn't know? Yeah, it didn't matter, because I had a job to do."
Samus Aran is now and always WAS a rarity- nay, a unique variant. She's a super hero who also happens to be a beautiful woman. Most of the time you're walking down the street when some creator throws a oversexualized supermodel at you, and after a two hour cutscene or 12 page image gallery you find out that she also has some battle abilities.
I don't mind when an artist decides to show us the woman under the suit - BUT STILL WEARING ANOTHER SUIT, INTERNET. But I do mind when it's obvious that whoever was at the art desk was... I can't come up with an art double entendre. Something about an easel? I don't know. I don't want horny dudes drawing while horny, otherwise characters get stupid and slutty for no reason.
COULD Samus Aran ever wear those ridiculous Combat Jump Heels? Yeah, sure. Provided she was stuck somewhere without her power suit and then KILLED those ridiculous heels' original owner, some alien race with ridiculous stiletto-like feet, and took them for herself in order to complete a mission. Would she keep them afterward and add them to her wardrobe? Fuck no. She usually even throws away all of the missiles and beam upgrades that I lovingly give her. Women, am I right, bros?
Some dude was at the drawing board late one night when he'd really rather be cleaning his brush (There's the double entendre!) and he drew some sexyheels on Samus. Then his boss saw them, and rather than lose his job after admitting he was gently applying a small fetish to the subject while getting PAID to do so, at overtime rates, mind you, he just made up some in-game use and bam, now the character will be permanently cheapened because of it.
There's an argument raging that this doesn't change the character, because there's other characters just like this already. Yeah, it DOES change the character. Because Samus WASN'T the heeled-super sexy sex avenger using sexiness to save the sexually charged universe. She was a soldier in a armored combat suit who fought a one human war against amoral genetic monsters being bred to dominate the galaxy by an illegal pirate force led by a sentient biological computer. Then, when that job was done, we could acknowledge that she was also an attractive female. It was something different, and now it may be endangered.
