Have the Marsblade FMT ones and love them...well, almost. The skating aspect is spot on. I wear Makos like one of the above posters and they feel almost identical.
The Verbrero boots are terribly uncomfortable, but this may be due to the hockey laces that came with them. The normal laces slide through the plastic holes and you are unable to tighten down the skates properly... I even use lace hooks. I just bought some waxed laces which will hopefully solve this problem. Complaints about the Verbrero boots are common, I guess. Wondering, while I type this, if the laces are the problem. We'll see what happens I guess.
Overall, I love the feel of the Marsblades. I can do many of the same edgework drills I do on ice skates. Even the one foot backward inside/outside edge drill.. don't know the name. Backward skating is a dream on these. C-Cuts, no problem. The skates do force you to maintain a proper hockey/skating position. Hockey turns are super tight. Inside edge turns...awesome. Outside edge turn...awesome.
I don't play roller hockey, but play ice. I bought these as a training aid and I can tell you they are as advertised.
I liked them so much, I have purchased (through kickstarter), the Marsblade Ice Holder. They are supposed to ship next month, so we will see how those are. Pretty excited.
