User blog comment:Teridax122/What are Ultramen wearing, clothes or nothing. And what is their skin color/@comment-1030114-20170709004054

From the way I look at it, some Ultras do seem to wear gloves and boots over their hands and feet, while others don't. It's a bit like how Toho explained the air holes in the Showa Godzilla suits to be 'gills'.

Who knows, perhaps Ultras with such visible 'gloves' and 'boots' in fact just have really strong ankle and wrist joints.
