I sailed ok last week qwith the new Futura without straps problems.
My foot size is 42 but i have a wide foot so sometimes i have problems to find acurate shape shoes for my foot.
I sail with ATAN boots ( the easier boots/straps i ever used).
- Release a bit straps screws.
- open all the velcros/zippers.
- Put your feet inside.
- Force with your foot to open the strap.
- Tight screws.
Releasing the straps screws allow neopren behind to strech a bit more and let you open more the straps.
