Cut animation sequence length

I have a walk loop that runs too long, as in within the sequence, the skeleton takes 3 or 4 steps. Is it possible to have a blend animation only use part of the sequence and loop that part? I think this is the root of my character sliding while walking.



Yes, in Persona move the the red box on the bottom to the last frame you want right click it and a menu should pop up with the option to remove frames.

Thank you!
