TYR Burner Fin 2.0 Swim Training Fins Black M (Medium) - Natural Rubber Short-Blade Propulsion

The TYR Burner Fin 2.0 Black M is a medium-sized, natural rubber swim training fin engineered to boost kick propulsion and refine stroke technique.

Designed for swimmers who want quicker, more efficient leg movement, the Burner Fin 2.0 blends a short-blade profile with a thickened foot pocket and no-slip heel base. Built from 100% natural rubber, this fin focuses on comfort and controlled propulsion so athletes can train proper cadence without sacrificing fit. The medium size (Men’s shoe 7–9 / Women’s 8.5–10.5) comes in a bold red color and is part of a color-coded sizing range to make selection fast for teams and coaches.

How does the Burner Fin 2.0 improve kicking technique?

Its short, rounded blade encourages quick, compact ankle motion and reduces drag caused by excessive leg extension. This promotes a higher kick rate and helps swimmers feel the correct muscle engagement for better stroke rhythm.

• Short blade design for rapid, controlled strokes.
• Rounded edges minimize turbulence and false propulsion.
• Promotes ankle flexibility and faster turnover during sets.

Will these fins stay comfortable during long training sessions?

Yes — the Burner Fin 2.0 uses thickened, soft rubber foot pockets that cushion the foot while still transmitting power to the blade. A universal non-slip grip on the heel base reduces slippage, so you get consistent contact and fewer rubs during repetitive kicking.

• 100% natural rubber for resilient, comfortable fit.
• Thickened pockets protect against heel and toe discomfort.
• No-slip heel base keeps fins secure through sprints and drills.

TYR offers this fin in five color-coded sizes to match common shoe sizes; the medium listed here fits Men’s 7–9 and Women’s 8.5–10.5 and is red. The color system helps teams quickly issue the correct fit for each swimmer.

How is the Burner Fin 2.0 constructed for durability and performance?

The fin’s one-piece natural rubber build provides both toughness and flexibility, surviving routine pool wear while maintaining blade response. The integrated heel grip and reinforced pockets are engineered to reduce common breakdown points and sustain repeated training use.

• Single-material natural rubber resists cracking and compressing.
• Thickened foot pocket for extended durability and comfort.
• Rounded blade edges designed to avoid premature wear.
