Default Shark outdoor wheels?

Has anybody tried these? Might have some advantages in the rain or on dirty surfaces.

They skateboard wheels are even crazier looking.

I would like to try them, but my sense is that their contact patch is ~50% too little to avoid lateral slipping and consequential wheel abrasion until the wear steadily increased the contact patch area.

They clearly would be good for skating in the rain

If I got the 70mm 80A MAKO version, it could wear down to around 66-68 mm OD before contact patch grew enough to allow enough grip for the slipping wear to cease, but I haven't been willing to gamble yet. Like you though, I am still curious. Especially with the all time wettest June record for chicago about to be established.

1. they seem a bit pricey for plastic hubbed wheels
2. 58mm tall seems short for trail skating. You'd get better roll for the push with a taller wheel
3. Just imagining pebbles and other stuff that would get stuck in those grooves.

Interesting....but not for me.

Got to pay for machining those "Fancy" (and pricey) urethane molds!

As I said above, they have a 70mm version that could work well outdoors once it wears down some.

I've tried the 'outdoor wheel' design (in an indoor duro... 95A), both indoors and outdoors.
They were OK for both... maple floor with 1 year old Roll-on coating, and smooth, shiny concrete), but fantastic on neither.
I actually tried a few laps on them during warm-up's at Nationals last year...
the plastic hubs really slow the wheel down.
Nice and light though.
The big zig-zag grooves offer no discomfort when rolling.
I thought the wheels performed better on the shiny, smooth concrete floor (derby track)... minimal slippage, easy to maneuver, light weight.
