No, they really did not. For Shizuo, although he feels the collision it's less painful for him. In fact it just feels as if he smacked against a pillow or a cushion. Unfortunately, that cushion is a young girl's face so when he finally stops about a foot above her, he turns back down to look at her.

"Aah, shit, you all right, Kotori?"

She'll have to excuse his language, but he's swimming back, a hand reaching out to her face because he really hopes he didn't make her nose bleed.
