Reddit reviews Roller Derby Zinger Boy's Roller Skate Size 06, Grey, 6

i'm two weeks in, my team practices 2x a week but i can only make one most weeks because of an evening class: i want to get better at skating outside of that since once a week is not a lot, but i am a broke grad student and will have to save for a while before i can afford good skates. would it be worthwhile to get some cheap-ass children's skates (looking at these specifically) for outdoor use while i'm working towards that mst, or would that money be put to better use elsewhere? (i mean obviously it would be better not spent on amazon but what can ya do)
