I am over 100 kg and Jackson is stiff enough for me. In fact if you look at the picture below you can see me stood on it to show how much it flexes......
Jackson is 45cm wide this is on the website the track width is not (I will make a change there thanks for the tip) but I did assume that people would notice our foil plate is 165mm x 90mm and assume that it fits our foil board!
The elevated rails never come into play strapless or striped. I have size 45 feet and I attach a picture of my foot in the strap.... as you can see there is plenty of space even for much bigger feet than mine.
The trim tracks are at 90mm spacing, this is the most common foil plate spacing. Zeeko use 90mm for sure last year and this year, previously I don't know sorry.
We don't sell from our webpage so we don't put pricing or availability there, this is info you need to get from a dealer.
If you send me a mail on firstname.lastname@example.org
I will put you in contact with your nearest dealer.
