With a quarter of the season behind us, the 2025 MLB campaign is in full swing. It's too early to see who the true contenders for the World Series as well as end-of-season awards are, but at this juncture we can crown Nike as true innovators of the on-field jersey movement in the 21st century.

The latest proof comes in form of the brand new Nike Air Max 270 MLB City Connect Pack, which drops today across select retailers and Nike's online store. The collection takes inspiration from all 30 teams' unique City Connect uniforms, transforming MLB's boldest jersey designs into street-ready sneakers.
Celebrating Baseball's Fashion Revolution
Since launching the City Connect program in 2021, MLB has gradually introduced alternative uniforms for each club that represent local culture rather than traditional team branding. Nike has been instrumental in this movement, working with clubs to develop distinctive looks that resonate with younger fans while paying homage to each city's identity.
Southern California designer Mark Guerrero, who worked on several City Connect uniforms, explains the crossover appeal: "Baseball has always been as much about style as it is about sport - fan traditions, ballpark fashions, the way players wear their uniforms. The City Connect program just formalized that connection, and now we're seeing it spread beyond jerseys into lifestyle products."
Sneaker Technology Meets Baseball Culture
The Air Max 270 model provides the perfect canvas for MLB's diverse color stories, featuring a large Air unit in the heel and a lightweight mesh upper. Key details include:
- Team-specific color blocking matching City Connect palettes
- Subtle embroidery of city coordinates on the heel tab
- Unique graphic insoles featuring city landscapes
- Team logos rendered in rose gold metallic on lace dubraes
Notable pairs include the Boston Red Sox "Flying Philly" edition with liberty bell details, the Miami Marlins neon Coral design, and the stunning Seattle Mariners cream/teal combo that mirrors their new weekend alternates.
