With the Roger Pro Fire, On’s latest performance tennis shoe—this one in a bold pink-and-“flame” colorway—the Swiss brand is back with a shoe aimed at aggressive baseline players. “The Roger Pro Fire was made for frequent, high-level, competitive tennis players who need their footwear to play as fast, strong, and aggressive as they play,” says On’s tennis product strategist Edwin Janes. “Players who favor an attacking baseline style and need a lot of protection with sliding will have a great option in the Pro Fire.”

Named for Roger Federer, obviously, the new shoe model has a following on tour, with Flavio Cobolli first switching to the model, followed by Joao Fonseca (which leaves Ben Shelton and Iga Swiatek still sporting the Roger Pro 2). Underfoot, the new non-carbon-fiber Speedboard plate extends under the forefoot, designed to support energy return during lateral movements while remaining flexible under the toe box. There’s also a softer foam for shock absorption, encased by stiffer foam for stability. The upper includes overlays and reinforcements to protect the lacing on the medial (inside), adding durability when sliding.

“When we kicked off the Roger Pro Fire, the ambition was to create a shoe that was more rugged and protective in what it provided to high-level players,” says Janes. “Where the Roger Pro 2 was designed for more all-court play and agility, we focused on dialing up the durability and stability on the Pro Fire for aggressive lateral movements and sliding.”

Janes says the team is always looking to identify gaps in the range—the performance range includes the Roger Pro and the Roger Pro 2 on the high-performance side, and the Roger Advantage Pro and the Roger Clubhouse Pro as everyday court offerings—and Federer and the On team saw a need to accommodate the “modern-day explosive and aggressive player, one that slides to corners even on hard courts and goes for aggressive cuts.”

Along with the bold pink/flame launch colorway, On will offer a limited-edition black-and-pink design. On’s hoping it all equals fire on the feet.
