For some shoppers, entering a new clothing store can be intimidating. There are new products, different designs and unfamiliar staff. However, Rod Rosales, a street-wear curator, goes above and beyond to maintain a comfortable environment in his shop.

Sitting on the corner of Cypress and Route 9, SizeRun Supply offers a unique set of clothing designs as well as a space for musicians, athletes, skaters, artists, collectors and many others to connect. As the SizeRun founder and owner, Rosales has taken great measures to ensure that his store is more personal than similar retail shops.

Given its convenient location, SizeRun Supply is a popular destination for many students from the high school. Junior Ben Lindblom recognizes the distinctive appeal of the store.

“Looking past the clothing and shoes on the wall, it is truly an experience to be had. Whether it’s the music, the soccer or skateboarding on the TV, or just the people in the store, SizeRun is one of the best experiences to be had inside a store in all of Boston,” Lindblom said.

After moving from California to Boston, Rosales gave up his career working with corporate athletic brands to pursue his lifelong dream of owning a store that was true to who he was. An important aspect of his store is the unique atmosphere it offers.

However, Rosales pointed out that maintaining a business requires a lot of effort.

“Running the store in general is tougher than you think. I’m a creative person. I love creating products. I love designing, but from an operational standpoint, it’s tough,” Rosales said. “There’s a lot of moving parts and you have to have a great support system that you can trust to help build the vision you have.”

Throughout his career, Rosales has prioritized the goal of staying authentic throughout the ever-changing world of fashion.

“The tough part is staying on top of trends and seeing what’s happening in the market, but also creating it through your own lens. There’s really no challenges other than just trying to stay ahead of the game and evolving because I feel as a creative person in business, if you don’t evolve and change, why do you bother?” Rosales said.

One of Rosales’ favorite parts about owning SizeRun is the ability to connect with and mentor local youth.

“I love to work with the community. Students in local internships come here to help out for advice and consulting, which I love because I love kids,” Rosales said. “There is just something about Boston that doesn’t have a lot of outlets for the youth. I love to be part of working with kids who want to create products and who have a passion for it, but give them a realistic idea of how it really works.”

Lindblom appreciates Rosales’ outspoken personality and finds it to be an endearing aspect of the store.

“As you walk in you can see Rod’s vast collection of new and old Supreme, the thing that draws you in the most is his personality and his friendly nature. I find myself in the store sometimes for an hour just talking to Rod about what’s going on in the world of design or even just what’s going on in terms of sports or school,” Lindblom said.

One of the reasons the store has gained so much popularity is through well-known celebrity appearances such as Ian Conner, Jaylen Brown and Playboi Carti, who enjoy the store’s special environment.

“I get to work with local talent such as musicians and athletes, and I probably would have never expected for us to be in this position,” Rosales said. “Many artists come here because it’s a family environment where people are just hanging out and there’s no pressure of me trying to sell products. It’s a hangout. I think they continuously come back here because they love the intimate and cozy atmosphere.”

Whether raising funds at a sneaker convention for the Brookline Teen Center, or donating proceeds of a T-shirt collaboration with Jaylen Brown to the Brookline food pantry, Rosales often uses SizeRun proceeds to help out local events.

Junior Jared Collins recognizes and appreciates his generosity.

“SizeRun has helped out the community a lot, which makes it feel a lot more personal and less of a big corporation,” Collins said.

Going on its fifth year, SizeRun continues to gain more popularity and success. At the end of the day, Rosales thinks that his hard work is showcased throughout his store.

“It’s not all glitz and glamour, and it’s not slapping a logo on and selling a million. You have to be really thoughtful about how you make products,” Rosales said. “And I think that’s why people love to shop; people recognize that here, and that’s the reason why we’ve been here for this long.”
