I bought these to replace the 50mm flat top footholds I originally had on my board as I felt they were a bit big for my liking. On initial impressions I didn't think the replacement would make much difference, however i was wrong. These feet are so much better as they are positive but they require you to place the toe very precisely from the start as you cannot rotate between edges of your shoe very well. These feet have added so much to my board and i feel the next level is not far away
