I got the ones with the gel inserts and they were a little uncomfortable for the first week or two I wore them. I’m an electrician and wear them 40 hours a week. They can be a little stiff on cold mornings until your body heat warms them up, but once warm, they are the most comfortable and best protection I’ve tried. They save my knees multiple times a day. My only complaint is the plastic buckles are weak and a tad brittle. I snagged a strap on a ladder one day and snapped one. Luckily they came with a spare buckle in the mesh carry bag.
