Question: can they be used outside on concrete
Document: The company worked with me to cancel this order after it shipped but I did look inside the box before returning and noticed these skates looked used.
one of the skates looked used when it arrived. wheel was dirty and the leather was a yellow brown. I must say though as far as customer service I can always be counted on to have things taken care of.
I would not recommend them for a teen or experienced skater. They aren't made as well as some of the other brands. But the price was good for the skate. Oh and I bought the "used" skates for less than 30.00 with free shipping. They were in excellent brand new condition. They were not used at all.

these are great for starters and that is exactly what she is. i think they are kinda cheaply made and the shoe strings are rediclously long.
spending many hours of fun with these skates. they fit well and are comfortable and cute on my feet. thanks
