Great Product

I now have both the 3.5” and the newer 4.5” push-up grip spikes. I bought the newer 4.5” spikes because I was curious if there was much difference vs. the smaller 3.5” grip spikes in effort. Both sizes are relatively hard, but I think the larger diameter ones are slightly easier, pressure is more distributed on the hands and because of the increase in mass I.e they don’t shake as much and are more stable. That’s my two cents……you won’t go wrong with either size!

Terrific quality and feel, these are a perfect compliment to the taller, larger pushup globes I bought years ago from you!
