Equestrians: tall boot crisis heeeeelp (sorry for random post)

Just a silly gal
Hi friends I had a riding lesson today and when I was done I noticed that there was a rip on the inside of my tall boots! They’re Mountain Horse boots and I’ve had them for about 5 years and they’re so comfy and I love them and I don’t want to spend the money on new ones/ deal with breaking them in. Does anyone know if I can get them fixed somehow? 
Sorry for the non <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> related post I tried googling this my little situation and couldnt find anything thanks my dudes
