إسفين القرفصاء الفليني

The natural cork surface gives you just enough grip without tearing up your shins, and it’s surprisingly firm under a loaded barbell. I’ve been using it for heel-elevated squats and my depth feels more consistent every session.

My knees feel way more stable during warm-ups now, and the cork grips my shoe better than rubber mats ever did. It’s solid and doesn’t slide no matter how much I’m sweating.

The cork surface gives just the right amount of grip under my heels without slipping, even when my socks are a bit sweaty. It’s solid enough that I don’t feel it compressing under a loaded barbell, which was my main worry. My squats feel noticeably deeper and more stable on my second week using it.
