Here are 2 stretches that i feel in my achilles.
Get into this calf stretch (if u do the stretch with ur shoes and socks off, u will have a better range of motion.)
Try to put the front foot as high as u can on the wall without the heel leaving the ground. Keep ur back heel on the ground. Now bend ur knee and try to make it touch the wall.
try it and if it doesnt work ill try to explain it better.
the second one is-
sit down on the ground and put ur hand over ur toes so that the point of ur fingers are over the balls of ur feet. Put ur other hand by ur heel of the foot ur stretching.
Pull ur big toes back (not TOO hard)and with ur other hand push ur heel forward.
I think thats an achilles stretch correct me if im wrong.
Hope this helps.
PS the descriptions are kinda funky so if u need a better one just tell me.
