Buy some five tens first and never look back.
I use five ten impacts and saints. I like the little bend in them to help cup your feet in, look at the side profile. Don't think I slip much or ever as the only time I remember it was dry. So prob my fault. Never had a problem with them even when plastered with mud.
As others have said when you take the washers out you will think twice about pin hight. Plus another manufacturer reduced them because five ten changed the layers of rubber on their newer shoes and longer pins were causing that floating feeling.
First paragraph. "How would shorter pins be more grippy? Most Burgtec users now stand on the shallower sole of the Impact VXI shoe from 5:10, the long pins can contact the harder inner layer of the sole not allowing the shoe to fully sink on to the pedal. Using shorter pins the Stealth Rubber will contact the pedal body giving more feel and eliminating the chance of floating on top of the pins."
