There are no differences between male and female right? Wrong. One has been clearly demonstrated by Genome852 in a video that shows when it comes to leaping the female Barbarian is somewhat better at it than her stockier male equivalent. In his demonstration he has the Legendary Lut Socks equip which is what is enabling them to jump three times in quick succession. Even though she appears to complete a Leap quicker than the male it doesn’t appear to have any impact on gameplay and is more a curiosity.
You can see the boots in action in a regular gameplay video of a male barb here. I only play female characters so I’m not familiar with the males to be able to notice a difference in skill animations between the sexes that may impact gameplay and I haven’t heard reports of any until this video appeared on reddit.
