OK well I went ahead and ordered them

Might as well spend some money to have something nicer... I don't want to wear gloves that feel like I'm wearing pillows on my hands. Hopefully these will fit nicer to my hand.

The $19.99 Wal-mart ones didn't fit well, there was a seam rubbing on my fingertips that was annoying, the lining kept bunching up, and my hands sweat a TON in them. Also since they were elastic with no means of tightening them in certain areas, the very back of the glove was too tight on my forearm muscles while the wrist area was loose. They would shift around on my hand too. They also just kinda looked like cartoon gloves

Now, should I hit the heavy bag with these on or only use them for sparring or focus pads? I have some bag gloves already but they are very light, is it better if I hit the bag with these gloves for a better workout, since they weigh more?

Also will it ruin them hitting the bag with them, wear them out fast or something? They are leather and my heavy bag is vinyl.
