Also, please take one more note from my book of misguided attempts.
When I got new skates I thought, yeah they feel good? It wasn't until I skated outside multiple times that I realized they were way TOO BIG.
Now I couldn't return them because I already ruined the wheels.
Skate inside on a clean floor before you make that final decision. Even if it's in your house. You'll save yourself a world of trouble.
