Sock and apparel brand Bombas and nonprofit Soles4Souls started with simple product donations. Seven years on, the arrangement has become a multi-year collaboration that creates value for both organizations, and it shows what separates a purpose-driven partnership that compounds from one that expires with the campaign.

"The ones that really matter, that really move the needle are the partnerships that not only last over time, but you learn from each other," Buddy Teaster, CEO of Soles4Souls, said on a recent episode of "Reimagining Retail." "It's not only OK, but encouraged to talk about the business value."

Bombas has distributed millions of pairs of socks through Soles4Souls' network since 2018, scaling fast without loosening its mission-driven commitments. Kelly Cobb, vice president of impact at Bombas, joined Teaster to discuss what separates enduring partnerships from one-off campaigns.

Alignment over transactions

The partnership began when Bombas, founded in 2013 with a mission to donate socks for every pair purchased, sought distribution partners that could help scale its giving model. Soles4Souls, which repurposes shoes and clothing to create opportunities for people globally, emerged as a natural fit.

"It felt like a partnership that felt perfectly aligned," Cobb said. The partnership started with straightforward sock donations but evolved significantly in 2020 when Soles4Souls launched its For Every Kid program, providing new branded sneakers to children experiencing homelessness in public schools.

Pairing Bombas socks with Soles4Souls sneakers gave recipients a more complete package, and it turned two missions into one. This year alone, the program served 250,000 children, a scale Teaster said would be impossible without Bombas' participation.

Quality signals commitment beyond marketing

Product quality separates real commitments from box-checking. Teaster noted that while Soles4Souls works with numerous brands using buy-one-give-one models, many deliver "the bare minimum" to fulfill their commitments.

"The quality of the product is amazing," Teaster said of Bombas. "This is not the bare minimum, check the box. There's no disconnect between what Bombas says and how they act."

The authenticity extends beyond formal programs. Teaster described finding a basket of socks at Bombas headquarters with a sign encouraging visitors to "grab a pair, and when you find somebody who needs them, give them." Hours later, he encountered someone in need and was able to provide the socks immediately.

The clearest test of authenticity happens where no one is watching. A Bombas customer service representative, not someone on the impact team, could discuss the Soles4Souls partnership enthusiastically. That is cultural integration across the company, not corporate social responsibility parked in a silo.

Scaling mission without losing personal connection

Bombas has grown from distributing thousands of pairs of socks to tens of millions annually across a network of more than 4,000 nonprofit giving partners. The company surpassed its original 10-year goal of donating 1 million pairs far ahead of schedule.

Maintaining quality at this scale required deliberate choices. Cobb's team of four people manages the entire giving partner network through a combination of integrated systems and personal touchpoints.

"The number of giving partners that do email us like they're the only one makes us so happy," Cobb said. "It can't just turn into a machine. It can't just be an operation that's lost that personal connection."

Critical success factors include:

• Continuous leadership buy-in ensuring mission considerations in every business decision
• Technology systems that streamline distribution without eliminating human relationships
• In-person visits to partner organizations to understand ground-level needs
• Bidirectional feedback loops that shape product offerings based on recipient needs

Listening to distribution partners shapes what gets built. Bombas expanded its product line to include underwear and T-shirts based on partner feedback, which is what investing in culture alongside infrastructure buys a company at scale.

The business case for long-term partnerships

Sustainable partnerships need a business rationale, both organizations said, not just philanthropic intent.

"What's your business rationale for this?" is Teaster's first question when brands approach Soles4Souls. "That's the only thing that will sustain it."

Cobb agreed: "It always has to make business sense. It couldn't be sustainable if it didn't make sense. No matter what the ideals, the intentions can be in the best place, but if it's not going to allow your business to be sustainable and a mission to be sustainable, it may fail."

Teaster cited BioPed, a Canadian footwear franchisee whose CEO correlated shoe collection and mission engagement with better financial performance, which makes social impact a business benefit rather than a cost center.

The most effective partnerships acknowledge that both parties have business objectives alongside social missions. Talking openly about logistics costs, distribution efficiency, and operational realities strengthens mission-driven work.
