Night splints can help relieve tension in the fascia and calf muscle. There are many models. Ideally the night splint will pull the toes upward towards the shin while resting. This will prevent the fascia from contracting at night. Some are more sock like, like the Strassburg sock and others are smaller like this one: shopfootsolutions.ca/orthoactive-soft-plantar-fasciitis-night-splint/ - if you don't like sleeping with socks you may not tolerate these well. Stretching the toes upward towards your shin before you get out of bed can achieve the same effect.
