Ex-Reebok Execs and Former Athletes Launch Unsung to Challenge Nike

Three founders with Reebok pedigrees and college athletics backgrounds have spent two years building a training shoe aimed squarely at athletes Nike and Adidas have, in their view, stopped serving. The result is the Snapback Trainer, the first product from Boston-based startup Unsung, which released it after two years of development and testing.

The company's founders are Dennis Baldwin, Jody O'Neill, and Brianna Henley, all former college athletes. O'Neill and Henley previously held senior roles at Reebok. Their target customer is narrow by design: young athletes, roughly 12 to 24 years old, who train for sports such as hockey, lacrosse, softball, and volleyball.

Why build a new training shoe?

Baldwin argues the existing market fails these athletes on a technical level. Their training involves heavy lateral, side-to-side, and explosive movement under load — demands that running shoes, the default choice for many, do not meet.

"We were looking at the way young athletes are training, and looking at the shoes that are being worn," Baldwin says. "They're typically wearing running shoes, which aren't necessarily great for the type of training they are doing—lateral movements, doing things under weight loads. We needed something lightweight and responsive."

"We saw a gap in the market, so we designed a product that fits," he adds.

O'Neill tested the assumption directly before committing. "The energy in the market has been focused on the millennial doing boutique fitness classes; the shoe built specifically for athletes training for sports didn't exist," she says. "I called up some coaches and trainers working specifically with athletes, between 12 and 24 years old, and they unanimously agreed that they didn't have the right equipment."

Unanimous agreement from an uncounted, unnamed group of coaches is weak evidence on its own. But the founders pair it with a market claim: incumbents are losing ground.

Is the moment right to take on Nike and Adidas?

Henley points to recent history as proof that upstarts can break through. "What we've seen in the last five, 10 years, is that the incumbent brands have been threatened by upstarts," she says, naming On Cloud and HOKA as examples — both of which grew from niche positioning into genuine challengers.

Her diagnosis of the giants is blunt. "I think the big brands have become so broad and inclusive that they've lost sight of the future of sport," she says.

The brand name itself carries the strategy. Unsung, as Baldwin frames it, is "a brand that celebrates the behind-the-scenes stuff, not just the highlights" — the hours of training and practice behind on-field performance.

One caveat sits plainly in that pitch: HOKA and On succeeded by winning broad consumer audiences, not by staying niche. Unsung's bet on narrow focus is the opposite path, and the source offers no sales figures, pricing, or funding details to show how the company will sustain it.

What does the Snapback Trainer actually offer?

The shoe combines three specific technical features:

• A carbon fiber plate
• A stability wing
• Supercritical foam

Together, the founders say, these support speed work, multidirectional movement, and explosiveness. The shoe is designed to provide more stability than a typical running shoe while remaining nimble.

The company's most prominent endorsement comes with credentials. Former NHL center Patrice Bergeron, who played 19 seasons for the Boston Bruins, has joined Unsung as a strategic advisor after testing the product.

"I've tried it, and I have a lot of experience with training," Bergeron says. "It's hard to find a good training shoe. I was doing a lot of lateral movement, speed work, and agility work. Over time, you try different brands, [but I couldn't] find something that was as stable as I wanted. I think it's an amazing training shoe."

An advisor's praise is a testimonial, not independent verification. Whether Unsung can convert a genuine product gap into a durable business against Nike, Adidas, Under Armour, and New Balance remains the unanswered question — and the next two years of sales will matter more than the last two years of testing.
