Why 300,000+ families switched
“Best invention ever!” My 6 year old has been playing soccer, HATES shin guards and would fight with me putting them on. We bought the ShinDefenders and wore them for the first time yesterday. He LOVED them! I will be buying a second pair to have a back up!
“Amazing product, amazing customer service.” My son loves this product!! The company has been amazing to deal with, very prompt and responsive. Would 100% recommend.
Quick answers
Will they actually stay up?
Yes — the compression fit plus the silicone grip at the top keeps them in place for the whole game. No tape, no separate sleeve, no pulling them up every five minutes.
What if I pick the wrong size?
Every order is covered by the 30‑day risk‑free guarantee. If the size isn’t right, swap it. And if you’re ever between sizes, choose the larger one.
Can they go in the washing machine?
Yes. Machine washable and quick‑drying — no more smelly guards in the kit bag.
