How do I fix this lerp this float so it doesnt snap from animation to another

Im trying to get these animations to play smoothly but I cant get it to not snap between animations because the code changes the float to fast. I need it to basically lerp the variable.

here is my code using UnityEngine; using System.Collections;

 public class MoveAround : MonoBehaviour {
     public Animator anim; 
     public float rotationSpeed = 1;
     public float lerp = 0.1f;
     public float rotatsada; 
     void Update () 
     {
         float rotation = Input.GetAxis("Horizontal") * rotationSpeed;
         float speed = Input.GetAxis("Vertical");
         float rot = rotation;
         float sped = speed; 
         float lerpRot = Mathf.Lerp(rot,rotation, 0.1f);
         float lerpSpeed = Mathf.Lerp(sped,speed, 0.1f);
 
         rotatsada = lerpRot;
         if(Input.anyKey && !Input.GetKey(KeyCode.Mouse0))
         {
             if(Input.GetKey(KeyCode.LeftShift))
             {
                 anim.SetFloat("Speed", lerpSpeed);
             }
             else
             {
             anim.SetFloat("Speed", lerpSpeed * 0.5f);
             }
             anim.SetFloat("Direction", lerpRot);
         }
     }
 }
