I finally decided to buy prim feet and I ended buying these at Maitreya.
These are the best prim shoes I saw in Second Life. Only disadvantage is that wearing these shoes the ARC goes up very high, but that happens with all similar shoes. And there is FlexiHair out there that pushes up your ARC up worse than with these shoes.
The creator is very friendly and interested herself in making future updates less laggy.
Of course I won’t wear these shoes when battling (I mostly fight with bare-footed) but when going out for dancing they will definetely going to be my first choice
