Parents of young riders, these Acavallo Alupro Junior stirrups are seriously smart for safety-conscious riding! The patented side opening mechanism is brilliant - if your young rider takes a fall, the stirrup arm opens outward to release their foot safely, preventing dangerous dragging situations. The lock-and-release system is positioned about a centimeter above the tread, which is genius because it stops dirt and sand from jamming the mechanism while also preventing accidental foot slippage. Weighing 703g per pair, they're lightweight enough for young riders but still feel substantial. The extra large 10.5cm tread gives awesome grip and comfort, and they're rated for up to 80kg maximum load. The 90mm maximum arm opening accommodates most riding boots comfortably. Made in Italy with that quality craftsmanship Acavallo is known for, these stirrups underwent years of research and development to get the safety features just right. The injection molding technique creates a durable product that stands up to regular riding lessons and competitions. Perfect for young equestrians progressing in their riding skills - gives parents peace of mind while allowing kids to focus on their form rather than worrying about foot entrapment. Much safer than traditional stirrups, and the black finish looks professional and clean. Definitely worth the investment for any serious young rider's safety and confidence in the saddle.
