In my Orientation Warping node, there is a parameter called “Rotation Interpolation Alpha”. It is a Lerp from previous Orientation to new one. If you make that value higher, Rotation reacts faster and there will be less foot sliding during turning. This issue you are having looks very similar. Also you can change the “Base Speed” of Speed Warping node dynamically by using the Root Motion Speed curve as mentioned. This will also help for less foot sliding in general. To, get the speed curve from root motion animation there is a Root Motion Extractor plugin from Yaki Studios or you can do it yourself with Animation Modifiers.
