I would highly recommend trying on the different size tips in the box. The sole is a bit stiff but light weight. I will keep it at 4 stars because I still love this keyboard and a resolder seems to have fixed it? But if I hadnt done that I probably would have had to try to get a warranty on it if I even could. Now, the GoXLR and GoXLR Mini are worth looking into. absolutely loved these little shoes! It looked a bigger than my last one probably cause of bigger battery. The articulation is standard marvel legends. LOVE these slippers! Bought the first one for my office back in 2016. But more importantly, I wear it everything single time I workout which is 4 or 5 times a week.
