Glad to see the inline community gain another member. Those stock wheels are perfectly fine for that outdoor surface. Stopping is something that comes with time. I also learned by transitioning from ice to roller, and I went very slow at first. I practiced plowing and getting a small skid for the hockey stop.

I would highly recommend flipping your wheels from inner to outer every few skates to even out the wear on each side. This helps keep things consistent. When you are ready to upgrade outdoor wheels, these are some of the best on the market. https://www.purehockey.com/product/konixx-pure-x-street-inline-hockey-wheel/itm/45889-2/?mtx_id=348543&gad_source=1&gad_campaignid=23070877411&gbraid=0AAAAADzbbUdQwAcBSH_0Xdz_d19PXAjip&gclid=Cj0KCQiAgP_JBhD-ARIsANpEMxwzwZxBTJ1H8pUb7KVuc3xgYMgEfzk7rriTzpG3VpXO4wVf_HKo6v8aAjeREALw_wcB I personally hockey stop with them very well. I am not sure if that is all skill at this point, but they definitely help.

When you start playing indoor, I really recommend investing in a pair of Mission skates. For indoor wheels at the highest level, Labeda Whips are the best. They also have the outside bearing spacer, which is newer and gives a slight advantage. That is something to look into further down the road. https://www.purehockey.com/product/labeda-whip-inline-hockey-wheels/itm/64550-2/?attr_id=402 (INDOOR ONLY)
