I have an upgrade set on my mission pedals where you replace the feet with some velcro kind of feet. Problem solved 
From google: not the exact product, but resembles it perfectly:

Mine was from stagetrix, but Thomann doesn't sell it anymore. Fortunatly, harley benton to the rescue: https://www.thomann.de/be/harl…QrMqqkpTvv74aAnSmEALw_wcB
Had the same problem a few years ago with a Dunlop wah. I ended up replacing the bottom metal plate with a wooden one, quite similar to the Harley Benton alternative above, except that I learned that due to the weight of the pedal, I would be safer to use velcro all over the bottom of the Wah instead of just at the tips as Harley Benton is doing it.
Yes, the pedal is quite heavy. I fixed the Mission Pedal on the floor board with the Harley Benton Wah Fasteners.
The future will figure it out, if it's strong enough... I hope so 
But btw, the Remote is quite heavy, too. And it stays on the pedal board with just two velcros, even if the board stands vertical.
That really surprised me
