I’m not an expert but seems too light.
I’m currently building another pocket and I have 2x6oz of carbon and 6oz of glass on each side + a strip of 12oz carbon on the length of the board
+ wood stringers
I have been using vibram 5 fingers for one season. The very light water specific model model.
Granted, only in fresh water, no sand... perfect feeling strapless. Still OK in straps. And I have not cut my foot this season!
I asked the same question last year. Search on kiteforum.ca
I got lots of recommendations for a flysurfer Viron (4m or 6m). I could not find one used, so ended up buying an ozone access 4m to get my 10 yrs old to practice on skis in light wind.
