The gloves are shaped to fit in the hand during use. The glove size is suitable when it fits very snugly at the top. You can grab the leather from the side of the palm, leaving the edge of the glove to detach from the side of the hand by just a few millimeters. However, it is a good idea to have a few millimeters of space at the ends of the fingers at first, because in use the fingers of the glove shorten a bit.
