Hi!
I’ve Been looking to get back into skating. I started at the beginning of last year (2020) and was skating for about 1-2 months before covid happened

!!
Since lockdown is being lifted I’m looking to get back into skating and get new skates since my current ones are for more recreational skating and don’t offer much support, so I wanted to get something stiffer
that will last quite a while since I am a fairly fast learner. Or at least last into jumps and turns.
Before lockdown I was doing crossovers both ways, arabesque forwards and backwards, Mohawks, 3 turns, small turns on the spot, one foot glide backwards and forwards, backwards to forwards (and vice versa)etc. So I am somewhere at a beginner- advanced beginner level I think?
I’m 15 almost 16, about 5’8 in height And fairly slim. I do have quite narrow feet so was advised on risports by a fitter. I’m looking to buy skates second hand and had the opportunity to get risport rf3’s with an MK professional Freestyle blade but I’m kinda worried That might be overbooting?
The other option is risport rf4’s which the fitter did recommend to me however didn’t have my size. But luckily I managed to find some online however the blades are quite rusted and I’m not sure how easy it is to get rid of rust.
I have tried to do some research as well but it was a bit hard to find much on weather rf3’s are ok for my level. If not I might have just stick with my ‘soft skates’ (sfr serene) for now and hold on to the rf3’s until I reach slightly more advanced levels!!
Sorry for the lengthy post but would anyone be able to give me any advice on this?

Thanks!
