Those Vik-max skates look almost exactly like something they sell at the local sporting goods store. Some of the kids show up in those for group lessons. They're definitely for the skating on the pond/ public session crowd.
What level is your friend at? Is this her first time taking group lessons? I'm guessing yes, otherwise she'd have some idea of what she needed. I'm assuming the riedells are at the same level. This would probably be better than any rental skates, and might get her through gamma (or whatever they're calling the levels these days....I did ISIA), but she'll break them down pretty fast, I expect, and will want to upgrade.
At best they might give her an idea of whether she likes skating enough to commit to better skates. I know the issues you have getting boots, so I would say if it's this or rentals than get this. But if she already knows she wants to skate, it might be worth getting a better pair of boots. I had royals back in the mid-80's, which were then their upper-mid-range boot, if I recall (there was one model stiffer), so I can't comment on whatever the Royal has morphed into today.
Good luck!!!!
