Shock Absorber MAX vs Active D+ by Parfait: Which Sports Bra is Best for You?
If you’ve ever struggled to find a sports bra that actually supports a fuller bust, you know the pain: straps digging in, bands rolling up, dreaded uniboob, or bounce that makes running feel like an extreme sport.
I specialise in bras designed for larger cup sizes, so today we’re comparing two of our most popular high-support options:
Both are built for high-impact workouts and fuller busts, but they solve different problems. Let’s break it down.
1. Support & Bounce Control
- Shock Absorber MAX: Famous for its lock-and-load compression, this bra minimises bounce by holding your breasts firmly against the chest wall. It’s especially good for running, HIIT, and anything jumpy.
"I am massively impressed by how well my breasts are held in place with this bra. I run and I’ve never felt more secure in a bra. Would recommend it to absolutely anyone doing very intense sports!"
- Active D+ by Parfait: Uses a wirefree encapsulation design. Instead of squashing, it separates and lifts each breast while still controlling bounce. Great if you hate that “strapped-in” feeling but still want security.
"Love this bra. Very supportive, no squished boobs. Comfortable style. Highly recommend."
Alisa recommends: If your number one priority is zero bounce, go Shock Absorber. If you want support with shape, choose Parfait.
2. Comfort for All-Day Wear
- Shock Absorber MAX: Runs tight in the band (that’s how it delivers its famous no-bounce support). Many women size up in the band for comfort. Not one you’ll want to lounge in after your workout.
- Active D+ by Parfait: Much softer feel, thanks to moisture-wicking fabric and no underwire. It’s designed for high-impact training but comfy enough to wear walking the dog or running errands after the gym.
"I appreciate the wire-free design, which makes it much more comfortable for all-day wear. Support is excellent."
Alisa recommends: If you’re sick of ripping your bra off the second you get home, try the Parfait Active sports bra.
3. Strap Style & Adjustability
- Shock Absorber MAX: Has wide, padded straps — super sturdy, but fixed position only. You can adjust the length, but not the configuration.
- Active D+ by Parfait: Features convertible straps that can be worn straight or crossed at the back. Crossing them often gives extra lift and support, especially helpful for weight training or when you want the straps hidden under a racerback tank.
"Love the Parfait sports bra as I was after an adjustable AND wirefree style for a size 18G bust. . . almost mission impossible until I found Alisa and this shop. I'm not gonna lie, this isn't gonna give you the same level of lockdown as the Enell SPORT (which I also bought and love) But for most workouts, it's perfect! I've worn it for everything from HIIT classes to hiking, and it keeps everything in place without feeling restrictive."
Alisa recommends: If you’ve ever had straps slipping off your shoulders, or you prefer a racerback fit, Parfait wins here.
4. Activity Match
- Shock Absorber MAX: Perfect for runners, HIIT lovers, CrossFit, horse riding and anything that makes you bounce. Think maximum control for maximum impact.
- Active D+ by Parfait: Great for gym workouts, walking, weightlifting and day-to-day comfort. Offers high support without feeling like body armour.
Alisa recommends: Match your bra to your sport. Shock Absorber for high-impact, Parfait for comfort + versatility.
5. Sizing & Fit
-
Shock Absorber MAX: Best for women in D–H cups. Runs small in the band, so check our Fit Guide
-
Active D+ by Parfait: Available in D–H cups. True to size in the band, softer stretch.
