How to Measure Your Foot
Place your foot flat on the floor against a wall. Measure the distance from the heel to the tip of your longest toe.
Always use the longer foot measurement for best fit.
Heel to Toe Length (in cm) is the most accurate way to choose your shoe size.

Sizes may vary slightly depending on foot shape and brand. This guide is for reference only.
Your racket is more than just a frame — stringing defines how it plays. The right tension improves power, control, comfort, and durability.
How String Tension Affects Play
More power • Larger sweet spot • Forgiving hits
Balanced power and control
More control • Precision shots • Smaller sweet spot
Recommended Tension by Player Level
Tension: 17–20 lbs
Power: High • Sweet Spot: Large
Tension: 20–24 lbs
Balanced power and control
Tension: 24–27 lbs
High control • Medium sweet spot
Tension: 27–30+ lbs
Very high precision • Small sweet spot
Key Considerations
- Performance: Proper tension balances power and control.
- Injury Prevention: Too much tension can strain the arm.
- Racket Safety: Never exceed the recommended tension.
- Beginners: Lower tension helps with mishits.
- Plastic Shuttles: Reduce tension by 2–3 lbs.
- String Lifespan: Depends on play frequency.
Final Recommendation
Beginners: Choose lower tension for comfort and power.
Advanced players: Higher tension gives better precision.
If unsure, always choose comfort first.

Specially engineered for strength and endurance training, this racket is a must-have for serious players, clubs, and coaches looking to build explosive power and improve shot control
Key Features
Heavyweight Design for Strength Training
The Isometric TR-0 weighs an average of 150 grams — almost double the weight of a standard racket. This extra weight adds resistance to every swing, helping players strengthen their wrists, forearms, and shoulders. Over time, this results in faster racket head speed, more powerful smashes, and better shot stability when switching back to your regular racket.
Full Graphite Construction
Built with a high-quality graphite frame and shaft, the TR-0 offers outstanding durability while maintaining a solid feel in every shot. The robust build withstands intensive training sessions and ensures consistent performance day after day.
ISOMETRIC™ Head Shape
Yonex’s signature ISOMETRIC™ design expands the sweet spot by 7% compared to conventional round frames. This means even with the added weight, players can maintain accuracy and deliver cleaner, more powerful hits during practice.
Air Resistance Mesh Cover
The TR-0 comes with a unique mesh cover that increases air drag during swings. This added air resistance enhances muscle engagement and refines swing technique, helping players develop smooth, controlled strokes that translate directly to match play.
Medium Flex Shaft
With its medium flex, the TR-0 offers just the right amount of repulsion and control, allowing players to build muscle memory and improve stroke mechanics safely.
Perfect for Clubs & Academies
Ideal for badminton clubs, schools, and academies, the TR-0 is widely used for training juniors and advanced players alike. It is an excellent tool for improving strength, stamina, and shot precision.
