a strap that goes from your bindings to your boot so in case you come undone you don't loose your board
At the very least you need a 'snowboard', 'bindings' that mount to the board and 'boots' that strap into the bindings. You can snowboard with those 3 things. You may also want to consider clothing to keep you warm and dry, like jackets, gloves, goggles and under layers.
Flow was the first to come out with a convenience style binding. That's what you are probably thinking of. All of their bindings work this way. K2 however came out with the Cinch in 2004 which operates somewhat similar but gives you the feel of a normal strap in binding.
I'm not sure where you heard that K2 bindings have design flaws, but I wouldn't agree with that at all. Although I ride traditional strap bindings, K2 makes the Cinch which is their take on a Flow styled convenience binding. As for their regular traditional bindings, I would say that it depends on which model you're looking at. All brands make cheap $129 beginner bindings that are exactly that, for beginners.
I would say they're more of all mountain bindings. You can take them in the park and they hold up, but I wouldn't say they're ideal for freestyle riding. Although they've gotten much lighter in the past few years, they are still heavier than a traditional strap in binding. If you are looking for a great and convenient freestyle specific binding I would go with some of the Ride Contrabands. They strap in with one strap so they're fast but they are designed for freestyle riding, with appropriately flexing straps and tons of cushioning underfoot.
yes you can snowboard in a wheelchair if you like in the united kingdom they make special wheelchair boards that u snap on your wheelchair and the have a strap and a buckle to strap on to the person so the don't fall they make them wide and long so that you can do tricks but i don't recommend them
You can but a new strap at sports chalet or any sport store, most skate shops, and any online snowboarding websight.
It depends on the size of the boot and the size of the binding. A traditional strap binding will work with any brand of boot, it is just a matter of whether or not the sizes are compatible. Attached is a link for a for a general binding size chart. Sizes do vary from brand to brand, but a general chart should point you in the right direction.
NO The Dredge boots are not snowboarding boots. They are casual snow boots with features that are used in certain snowboarding boots but are not meant to strap into bindings.
If you want a good stomp pad, get the Burton pad. Burton is very reliable and possibly the best brand of snowboards in the world. Its stomp pad has worked for me for 2 years, and it still has a lot of grip. You can't go wrong with a Burton stomp pad. However, there is a new stomp pad that is especially good for beginners called "Strap Pad," that is the only stomp pad that has a velcro strap that eases your ride on and off the chair lift. See strappad.com. It was considered one of the "Best New Products" at the 2009 SIA show.
Ride snowboards are good quality boards (i had one last year... DH) and its a great snowboard but i tryed a friends Burton love and it liked the feeling of it alot better. I would recommend ride snowboard but look around before you buy
Average woman's wrist is 7" so my guess would be about 7".
