Disappointed

I bought these for my teenage daughter, who runs track in high school. She was really excited to get her new spikes, and they look and fit great. But unfortunately the heel started to show noticeable wear after only two uses. The lightweight foam material at the heel is simply too soft with no added layer of traction or protection, and simply isn't durable enough for even light use. This is disappointing given how much we paid and how lightly they’ve been used so far. I expected better durability from a product like this.
