These things might be my favorite atomik hold set in general... They're pretty cheap, and they're screw on which is great, as you can put them anywhere you want on your board (without using up t nuts). I use them on my 40 degree spray wall, and bought them all in a single color, so that I can set problems and circuits that are "teal feet only" and they usually end up being super fun. All of these are pretty small, and some are relatively positive, however others are absolutely tiny and slopey, which really forces you to engage your core and focus on foot tension... either that or you're feet will cut.. good training either way!
