Those little lumps are only cosmetic I wouldn't worry about them. If you tire open the glove you'd notice the lumps as re just tiny prices of laytex dust particles. that normally break off over time from opening and closing your hands when the laytex foam rubs against the leather wrinkles on the sides of the gloves. Normally happens with softer laytex foams. But doesn't effect the performance of the gloves at all. Like I said just cosmetic no need to stress out about them little dust particles making there way from the sides of the foam padding.
