It depends on the board, your style of skating, your preference, and what wheel it is. Some 80a wheels will slide smoother, longer than others and some will grip more. Generally this durometer is common because there are wheels of this duro that can slide great and grip great as well. It is a great duro to experiment with, that way you will know what you want in a wheel next time you purchase.
80a. The higher the duro the harder the wheel
- footbrake: put your foot lightly on the ground as you're riding - airbrake: stand up really tall and wide when your riding (slows you down but won't stop you - sliding: I reccommend that you get yourself some sliding gloves, 80a up wheels and some pads and helmet and learn to slide because going over 40ks if you air brake you'll get speed wobbles and if footbrake and lose balance u'll most likley die or get seriously injured. if you need help look up how to slide on youtube.
If you are referring to inline hockey skates, then yes you can use then for general street skating. I would highly suggest that you purchase an extra set of wheels that are harder for street use. Most inline hockey skates have indoor wheels and they will wear down fast skating on a hard surface. You will need wheels with a hardness (durometer) of 80A or higher. It is not that difficult to change out the wheels, just need a skate tool.
The Electric Company - 1971 80A 5-80 was released on: USA: 6 February 1976
To determine if a hockey skate is an outdoor vs. indoor skate, it is really based on the hardness of the wheels. This is called the durometer. Usually an outdoor roller hockey wheels will have a hardness of 80A or higher, while an indoor wheel will be abound 76A. The wheels that come on a Mission HE1500 skate are 78A, so i would consider these an indoor skate. But you could use then outdoors, the wheels will just wear down faster.

The LCM of 5a and 16a is 80a
25a2 - 80a + 64
80a^3
√(5a) + 2√(80a) - 7√(125a) first square the whole equation [√(5a)]2 + [2√(80a)]2 - [7√(125a)]2 when you square a sqrt the sqrt goes away 5a + 4 * 80a - 49 * 125a dont forget to square the numbers outside the sqrts 5a + 320a - 6125a just add and subtract -5800a is your answer
It came out November 10th, 2006. It was Season 4 Episode 80a.
Cannot find a cross reference for an 80A, but if you rifle is a .22 pump, it is likely a Savage Mdl 29. These were sold by Wards as their Model 80. The Savage 29 was made from 1939-1967.
