I like to know how this compare to yonex as well, since the return policy at sportchek is good so i am not worry too much. if the shoes is too heavy then i will return it.
I am no where near playing professional level, nor aggressive. I do enjoy playing in club with friends weekly, and I enjoy having proper equipment and support, I am aging!! but below are some of my personal observation/opinion after owning both Yonex and Asics, I hope it helps others to decide, but disclaimer, I am not profession in badminton, rehab, sport injury, or selling shoes
from my experiences, 3 pairs of yonex shoe i own are about 30-50g lighter per feet compare to Asics. my current shoes is a pair of cheapo yonex Power Cushion 35. after i realize they do not last longer than Asics, I decided to get the cheaper one to save $$$. Yonex is definitely lighter, the support on the area the feet contact with floor is adequate, i prefer more support, and I assume it's a trade off between weight and thicker cushion at sole area. I do miss the feeling of wearing Asics. the Yonex offer a bit more support at the ankle area, maybe a bit higher in that area, I don't know how much actual differences this made on the actual playing on the court. MOST, if not all, players that I see, wear Yonex, so far I had been lucky, no ankle issue with Asics or Yonex, I had seen other players roll their ankles in their yonex shoes but since I am the only guy with Asics I wasn't able to see others roll over in that brand; I was told, combination of wrong foot work, fatigue over aggressiveness contribute to these injury.
like i said earlier, if this pair is too heavy then i will return to sportchek.
at the same time, anyone know what make a shoes having good "lateral support" ?
