Quick question to all VPD Air users - Do they stretch at all? I have a M and L and trying to decide what size to keep. L is comfy and feels a tiny bit loose around the knee area and just "sits" around my calf. M fits like a glove, no movement but a little tight around the back of the knee area when pedalling. I have a feeling they will stretch a little and would then be perfect. If not, they will be a little to tight forever!
I used mine for a week's snowboarding - they definitely stretched a bit.
I'd definitely keep the smaller one, i had the same issue and glad went for the smaller set.
I have the xl’s which felt a bit tight at first and now they feel great having stretched a bit
Consider that a pad that slides about a bit while you're standing around is unlikely to stay put anywhere near where you want it to be if you crash.
To be honest, and I love POC kit, if you're between sizes like this I'd seriously consider trying other brands until I found something that fitted properly.
