KS: Let’s change gears a little. How do you stay in shape? Personally, it’s hard for me because I don’t like to do a whole lot of other stuff besides surfing.
MM: Going to the gym can be pretty monotonous. I felt like I was getting a little too skinny, so I stopped doing so much cardio and started practicing Pilates and working more on strength training and toning. My lifestyle is pretty active, as well. I surf, I stand-up paddle-board, and I have a puppy now, so I’m always on walks and runs with her.

KS: You mentioned paddle-boarding—you just released your own line of boards, right?
MM: I started demo-ing some boards for Surftech, and I felt that we needed a new design for women. I was frustrated that I needed a guy to carry my board down to the beach. So we made one that’s lighter but still stable. They thought, For a girl, do we put a pink flower on it? I really wanted to do a black one, and they thought I was crazy. After the orders came in, it was 70 percent for the black [boards], so I was like, Yes! Told you guys! Not every girl wants pink!

KS: You have a pretty casual style, but what are your go-to designers when you feel like dressing up?
MM: As far as red-carpet style, I love Dolce & Gabbana, because their dresses don’t take away from the women who wear them. They’re really focused on tailoring and fitting the body right, nothing too crazy. They’re timeless, they fit great, and you always feel really sexy when you wear one.

KS: I don’t.
MM: They don’t fit your body well?

KS: No, not very well. I just feel goofy.
MM: Yeah, I could see that! Then, on my personal time, I love Alexander Wang and Rag & Bone.

KS: You’ve been working with the USO [United Service Organizations]. How did you get involved there?
MM: The USO has probably been one of the most rewarding and touching things I’ve been involved in. I would get a lot of letters from guys overseas asking for pictures, or even wives asking for pictures to send their husbands. So that was eye-opening to me. I would get to meet remarkable people, like a girl with a brand-new baby whose husband had been stationed in Afghanistan since before the birth. That’s real heavy stuff. It’s so important to remember not only what the service members are doing, but also how their families are sacrificing, as well.

KS: I just feel goofy.It’s definitely very humbling to see that kind of commitment. You’ve also been helping out organizations fighting breast cancer. How did that come about?
MM: I work with the Young Survival Coalition, which is a group that supports and educates women under 40 who get breast cancer. I was just floored hearing about some of this stuff, because oftentimes when women get cancer in their 20s and 30s, it’s much more aggressive. I also help raise awareness about skin cancer. Young girls would approach me, and it was so obvious they were using tanning beds and frying. Being the beach bum that I am and having that kind of image, I felt like it was really important that I got the word out there that I don’t do that.
