ひざ用サポーター (マジックテープ式)

this is particularly useful when you have to repeatedly kneel on tatami mats.

Bonne tenue avec ces liens élastiques pas de douleurs sur le genou

They are comfortable and works.I have tried them in Iaido,Karate,Kobudo and Goshindo.

Parfait pour les genoux fragiles en suwari waza

Ne pas oublier d’en commander 2 car vendu à l’unité

J'ai fait le tour de beaucoup de genouillères pour trouver celles qui seraient le plus adaptées à l'aikido. On trouve en France des genouillères pour les autres sports, mais il y a toujours un truc qui ne va pas, soit sur la compression derrière le genou, soit la rigidité de la coque, soit l'absorption pas terrible. Avec celles-ci, j'ai retrouvé le plaisir de pratiquer à genoux, et je la recommande tout autour de moi pour que le suwari waza redevienne sympa :)

So far, sewing in an additional Velcro was not necessary. Obviously, the material chosen (compared to my previous pads) is much better and they stay in place, even with less tightening.

As mentioned earlier, the knee support does what it's meant for. The only disadvantage can easily be overcome by sewing an additional Velcro fastener on the lower band (as mentioned by Anna below).
Maybe this can already be done in the factory?
However, I still like them!

未熟で板の間で膝をつく際にきついため、購入しました。
マットの上で膝をついたような感覚です。(痛くない！！)

市販のスポーツ用サポーターは、締め付けが強くて血流が悪くなったり、膝からズレたりしますが、このサポーターは上下のみマジックテープで止めるだけなので、ズレたり、血を止めたりしません。

2時間稽古しても、巻き直しは一度もありませんでした。
すごく膝が曲げ易くて、正座も楽です。

他社製品との比較ができないため、星4を付けていますが、ぜひ他人に勧めたいと思う品です。

The knee pads are different from what i am used to, I have been using soccer knee pads, these are light and have a low profile, they fit well and are comfortable.

These knee pads are the best I've ever used. They are comfortable and effective and also very light. With the velcro bindings above and below the knee, they allow for maximum comfort and they don't trap in the heat. The gel is enough to cushion the knee and protect from impact and pressure on the floor but no thicker than it needs to be.
The only drawback is I did have to sew on velcro in order to keep the kneepads secure in place.
And they don't last for ever but I've had one pair for a couple of years and that't pretty good going.
