Street hockey pads are not made to withstand extremely cold temperatures and are not made to the higher standards of protective ice hockey equipment.
the size of the leg pads
It is OK, but if you are above the age level of 6 i think, you can get seriously injured.
Depends what type of hockey you're playing. Minimum for ice hockey: Shoulder pads, gloves, shin guards, elbow pads, a helmet, breezers, hockey socks (to cover shin guards) ice skates, compression shorts that will hold a cup or a jockstrap and a cup, a hockey stick, ice hockey skates For roller, all of the same except: No shoulder pads, roller hockey pants and an inline girdle instead of breezers, no hockey socks, roller hockey skates instead of ice hockey skates For ice hockey goalie: Goalie pants, a goalie groin protector and cup, a monkey suit, leg pads, a goalie helmet with a throat protector (preferably), goalie ice hockey skates, a goalies glove, a blocker, and a goalies stick For roller hockey goalie: Same as ice hockey goalie except roller hockey goalie skates For ice hockey: An ice rink with nets on both sides of the rink and a puck For roller hockey: A roller rink with nets on both sides of the rink and a roller puck (yes, they are different from ice picks. They're made to reduce friction and slide better on floors.) For street hockey: Some sort of net, a ball or puck, and a stick I think I covered a good portion of it. If I missed anything, I apologize. It's a great sport, have fun!
the highest I've ever seen are the reebok revoke pro zone goalie pads...they are 1,900 bucks
you need Helmet,Stick, Chest protector, Catcher, Blocker, goalie Girdle, leg Pads, and skates
They would probably provide some protection, but friction on ice is less then on concrete, so I think the puck will have higher speeds, therefore you'll need thicker pads.
The hockey or ice hockey position is spelled "goaltender" (goalie).
Well they need a variety of equipment. First they need goalie skates and goalie pants. Also they need special type of pads to cover their legs, called goalie leg pads. A few other things are a goaltender chest protector, goaltender catch glove, blocker, goalie helmet, a goalie stick, and usually a cup.
