I love my old dragons, favourite shoe ever. The Sirius is a very good match, I've been really pleased with mine. Definitely my go-to shoe for everything I do now, indoors and outdoors. The fit and feel are very similar, I think they've tried to add in a little more toe rubber but they've kept the sensitivity with quite a supple midsole. Heel works better than the dragon I think. No hesitation in recommending them. On the flip side, I sent my old dragons off to llanberis resole before they were completely done in and he's done an amazing job resoling them so if they're salvageable that might be worth a punt.
