Rollerblades, that is...
The above are about 15 years old and have served me well. I "customized" them so that they could run 80mm wheels, but no larger. The padding finally wore too thin and both my ankles have been in pain.
In with the new...
I had been thinking of getting a pair that had 100mm wheels, but I decided that they may be too fast. I settled on the 2008 Speedmachine 6.0 Rollerblades, with 90mm wheels. With a carbonfiber and kevlar shell, I feel confident that my feet will survive any bullets fired at them.
Old and new...
I tried them out this evening and even though I was a bit unsteady, I managed to knock a minute off my time. I have a consistent 20 minute, 5 mile loop. It took me 19 minutes today and I was not pushing at 100%.
Looks like I may have to go 10 miles a day.
