Hi. I need some advice. Now that I have started to sail in waves it suddenly feels like my feet are too narrow for my footstraps (the straps feels too wide sideways). My feet slips out of the straps when attemting forwards and I don't feel "locked in" when trying to do some waveriding and other moves. Are there any brands making adjustable or narrower footstraps? Dakine?

Wait, wait, wait, did I get that right, you just started surfing in the waves and the first thing you do is throwing yourself in a forward?????????? What kind of fearless bloke are you. It took me 10 years of sailing to do that (ok I am a bit slow).
However, loosing the board in a forward can also have technical reasons, I had that at the beginning, when spinning to much horizontally.

PS: the previous advice is what I would suggest, try DaKine and play with different setups with the screws.

i've got a custom waveboard with no extra screw holes and i had exactly the same problem. No matter how tight i made the strap, i couldn't get the strap to grip the sides of my feet, only the top, and it made jumping scary. I tried padding out the insides of the straps without much success. So eventually i sunk extra plugs into the board to narrow them. Now it's as good as wearing booties, and certainly gives you alot more confidence hey! :)

i tried, but they were out of stock

every night sit with your feet in a bucket of chook poo half an our per night for 3 weeks.
I like my foot straps super big and loose for wave riding check out pics of Naish, Polokow, Justin Stock, Mattress Buster, Ben Arther, Bondy, Etc all these great wavesailers have huge footstraps for wave riding.

spend some time on dry land adjusting your straps. check if your straps have extra holes by removing them and inspecting them closely.if your board has holes closer together move everything in. but whatever you do, dont remove your clothes before loops as gooza recommends. that will only bring tears.
