I have a pair of Skike V 07s for $60 plus shipping. Can bring to JIBE. I thought of using them (as others have) for rougher terrain. While I think it would work pretty well - I'm not sure my skating skills are up to it and I think Rollerblades would be a better place to start.

The Skike has 6 inch inflatable tires and I will provide a spare inner tube as well. They are fun to use with ski poles on rougher surfaces, but be prepared for a workout. I can take paypal if that helps.

How old are these and what size shoe do they fit? Thanks!

I don't know how old they are. I got them used in Dec. 2014. This is a few models behind the current Skike. If you check the Skike web page (they have a US Dealer for parts) you might be able to find out.

As I understand it, they will fit a wide range of shoe sizes because they are adjustable. I actually attached a pair of cheap, old plastic rollerblade boots to them (which wheels removed) to prevent my ankles from getting too tired.

Here is a link to the US Dealer. You may be able to find more about the skikes on their web page.

I have a pair of these. The build quality on them is really nice, but I don't like the width of the tires. I wish the tires were just a little bigger in diameter as well. I think they would work well on short grass and they do work alright on hard pack sand.
