I can't walk in high heels, so this blows my mind.

It reminded me of the quote about Fred Astaire and Ginger Rogers, [About Fred Astaire] "Sure he was great, but don't forget Ginger Rogers did everything he did backwards...and in high heels!" -- Bob Thaves 1982 © NEA Inc.

According to an article in Huffpost Lifestyle United Kingdom, the group of Russian women competed in Bali, Indonesia and Huffpost had this to say:

Considering California's annual Mavericks Invitational surfing competition doesn't allow women to take part because the director says "we're not there yet", we'd like to issue a challenge to the lads. If they can surf in high heels half as well as these women, then I think "we're there".

Yep.
