Yonex Astrox 100 Tour Strung Badminton Racquet

Composition: Full Graphite, Weight – 4U (Avg.83g) , Grip size – G5, Tension: 20 – 28 lbs, Shape: Isometric. Isometric: The square-shaped Isometric frame shape is designed to keep vertical strings at a similar length, as well as the horizontal strings to produce an expanded sweet spot in all directions. Rotational Generator System: By applying the counterbalance theory, weight is distributed throughout the grip end, frame top and the joint for maximum control. The transition to the next shot can be performed smoothly, with rapid succession. Built-in T-Joint: Increases strength between the frame and shaft eliminating head twist for more control. AERO BOX Frame: Combines solid hitting feel and quick swing.

Double Guarantee!

Money-Back Guarantee: The proof of comfort comes from using your Feathersprings and experiencing relief. You have a full year to try your Feathersprings. If you’re not 100% satisfied, simply return them within your trial for a full refund of the purchase price. (Shipping and handling charges are non-refundable.)
Lifetime Guarantee: If the metal portion of your Feathersprings should ever break from normal use, and parts have been maintained, then we’ll replace your Feathersprings one time free of charge. It’s important to note, research has shown that feet change size about every ten years. So for the purpose of healthy feet, the Lifetime Guarantee is defined as 10 years. To properly maintain your Feathersprings and to ensure proper flex and support, metatarsal cushions and shoe protectors must be replaced regularly. Lifetime Guarantee requires you change metatarsal cushions every 3-6 months and shoe protectors every 6-12 months. (Damaged Feathersprings must be returned for free replacement.)

Your purchase price is for one pair of Featherspring™ shoe inserts.

NOTE TO DIABETICS: If you’re a diabetic, we recommend adding a Padded Covering to your Featherspring™ Foot Supports. YONEX MAVIS 350I BADMINTON SHUTTLECOCK
