Foot_IK Problems (Foot Placement Raycast

hi guys i have a question aboute this IK system i did follow a tutorial for this script but i am running in to a problem The IK Works but not correct i added a Debug.Draw so can see where the ray`s are and i seems that the Ik only works when the hit.transform.tag == "Walkable" hits the middle of the raycast so i basicaly starts the Ik on my players knee when it hits the tagged object does enyone know a sollution like am other offset or somthing? here is the script

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Foot_Ik : MonoBehaviour
 {
 
     public Animator anim;
     
     public LayerMask layerMask; // Select all layers that foot placement applies to.
 
     [Range(0, 1f)]
     public float DistanceToGround; // Distance from where the foot transform is to the lowest possible position of the foot.
 
    
     private void Start()
     {
         
         anim = GetComponent<Animator>();
 
     }
 
     private void Update()
     {
 
         if (Input.GetKeyDown(KeyCode.M))
             anim.SetBool("Walk", !anim.GetBool("Walk"));
 
     }
 
     public void OnAnimatorIK(int layerIndex)
     {
 
         if (anim)
         { // Only carry out the following code if there is an Animator set.
 
             // Set the weights of left and right feet to the current value defined by the curve in our animations.
             anim.SetIKPositionWeight(AvatarIKGoal.LeftFoot, anim.GetFloat("IKLeftFootWeight"));
             anim.SetIKRotationWeight(AvatarIKGoal.LeftFoot, anim.GetFloat("IKLeftFootWeight"));
             anim.SetIKPositionWeight(AvatarIKGoal.RightFoot, anim.GetFloat("IKRightFootWeight"));
             anim.SetIKRotationWeight(AvatarIKGoal.RightFoot, anim.GetFloat("IKRightFootWeight"));
 
             // Left Foot
             // We cast our ray from above the foot in case the current terrain/floor is above the foot position.
             Ray ray = new Ray(anim.GetIKPosition(AvatarIKGoal.LeftFoot) + Vector3.up, Vector3.down);
            
             if (Physics.Raycast(ray, out RaycastHit hit, DistanceToGround + 1f, layerMask))
             {

                 // We're only concerned with objects that are tagged as "Walkable"
                 if (hit.transform.tag == "Walkable")
                 {
                     
                     Debug.Log("raycast");
                     Vector3 footPosition = hit.point; // The target foot position is where the raycast hit a walkable object...
                     footPosition.y += DistanceToGround; // ... taking account the distance to the ground we added above.
                     anim.SetIKPosition(AvatarIKGoal.LeftFoot, footPosition);
                     anim.SetIKRotation(AvatarIKGoal.LeftFoot, Quaternion.LookRotation(transform.forward, hit.normal));

                     print("Hit");
