I'm new to the sport and still learning a lot of different things about equipment. I went to Play it Again Sports today and got a pair of Senior Reebok 3K (2009) skates today for 4$. Blades are a little rusty, got them sharpened and that took away a lot of the rust and got them ready for the ice again. I was mostly wondering if anyone knew if these skates were able to change blades on them. there is no screw inside the boot or anything on the blade holder, but I did see video of someone just popping the blades out of a holder. I don't think these skates are able to changed but I figured someone would be able to fully clarify for me. Thanks in advance
