Does anyone know if this is a good jumping shoe?
It's very light, which is one thing that I thought was different, at 5.8oz, compared to other shows like the CyberJump or TurboJump which are at 8 or above.
It's designed to be a hurdler shoe, but don't hurdlers also need excellent heel support?
Interested in buying it, but want to make sure that it's good pole vault and long/triple.

If you weigh over 100 pounds, this shoe is going to blow out after a few vault sessions. The reason jumping spikes are heavier is because they have to be to withstand the forces involved and still give you a stable platform to takeoff from.

Oh wow...I had no clue about that.
Well I'm on the verge of making the 4x4 team right now, which is why I initially looked into it, but it seems like now I should just go for 2 pairs...
