Spikes

Thanks for the feedback.
I was doing the hills in sneakers but figured the 10-30m acceleration work would be done in long spikes on grass. I didn’t notice the issue of footwear specifically addressed in the video (maybe I missed it?).

I’ve also been doing the tempo in sneakers. What would be the advantage to barefoot? I imagine it would be pretty impractical to check the entire length of the football field for sharp objects.
