Key Takeaways:
MLS laser therapy uses two synchronized therapeutic wavelengths to reduce inflammation and interrupt pain signals in the tissue—making it one of the more targeted non-surgical options available for stubborn plantar fasciitis. Many people in the Treasure Valley who haven’t found relief through rest, stretching, and orthotics alone are good candidates for a series of treatments, with many noticing improvement within the first few sessions. The key to realistic expectations is understanding that results vary based on how long the condition has been present and your individual healing response.
That sharp, stabbing sensation in your heel with your first steps in the morning. The ache that comes back after a long day on your feet. If you've been living with plantar fasciitis and heel pain for more than a few weeks, you've probably done your research—and MLS laser therapy has likely come up. The question patients most often ask us at Rocky Mountain Foot & Ankle is a simple one: does it actually work?
The answer requires more than a simple yes or no. Let’s take a closer look at what the treatment involves, who tends to respond well, and what realistic outcomes look like.

What’s MLS Laser Therapy, and How Does It Target Plantar Fasciitis?
MLS stands for Multiwave Locked System. Unlike older, lower-powered lasers, MLS technology delivers two therapeutic wavelengths simultaneously—808nm and 905nm—that work together to address both the inflammation and the pain signals driving your heel discomfort. As Dr. Roman Burk explains in this video, the synchronized wavelengths penetrate tissue three to four centimeters deep, activating anti-inflammatory pathways and reducing the nerve activity that registers as pain.
For plantar fasciitis, this combination matters. The plantar fascia is a thick band of connective tissue that runs along the bottom of your foot. When it becomes chronically inflamed from overuse, biomechanical stress, or inadequate support, simple rest often isn't enough to reset it. MLS therapy gives the tissue a targeted biological stimulus to interrupt that cycle.
What Should You Expect During an MLS Laser Treatment Series?
Each MLS session is brief—typically eight to twelve minutes—and non-invasive. Patients lie comfortably while the laser applicator is passed over the heel and arch. There's no heat sensation, no recovery time, and no medication involved. Most of our patients treated for plantar fasciitis complete a series of 6–10 sessions, often scheduled over 2–3 weeks.
Some individuals notice reduced morning stiffness after the first few sessions. For others—particularly those with longer-standing or more severe inflammation—meaningful improvement may take the full course of treatment. Because every patient's healing biology differs, our skilled Caldwell and Meridian podiatrists evaluate response throughout the series and adjust accordingly.
Who’s a Good Candidate for MLS Laser Therapy for Heel Pain?
MLS therapy tends to work well for people who:
- Have had plantar fasciitis for more than 6 weeks without full resolution through stretching, rest, and footwear changes.
- Want to avoid cortisone injections or aren’t able to receive them.
- Need to return to activity—running, hiking, or a physically demanding job—without a long recovery window.
- Want a drug-free, non-surgical option to complement custom foot orthotics or other conservative care.
If you or a loved one has an active infection, certain skin condition over the treatment area, or is pregnant may not be an appropriate candidate. Our doctors conduct a detailed evaluation and determine a clear diagnosis before recommending a treatment plan.
How Does MLS Therapy Compare to Other Plantar Fasciitis Treatments?
Generally, there’s a step-by-step approach. Initial care typically involves stretching protocols, supportive footwear, and custom orthotics to offload tension from the fascia tissue. When those measures don't fully resolve symptoms, options such as cortisone injections, shockwave therapy, or MLS laser therapy may be considered.
MLS advanced technology is also useful in combination with other treatments—some patients benefit from MLS along with PRP therapy when there’s significant tissue involvement. Our team at Rocky Mountain Foot & Ankle determines which approach, or combination, fits your situation.
What Results Can You Realistically Expect?
A systematic review of MLS laser therapy indicates that, when part of a dedicated treatment plan, it produces meaningful relief for plantar fasciitis, but it works best when expectations are calibrated to your particular circumstances. Generally, our patients with more recent onset and less tissue damage tend to respond faster. Those with chronic, long-standing heel pain may require more sessions and a broader treatment plan.
MLS therapy isn’t a one-session fix, and it’s not a substitute for addressing key biomechanical factors—tight calves, overpronation, inadequate arch support—that also contribute to plantar fascia pain. However, when used as part of a thoughtful, individualized medical strategy, it’s one of the more effective non-invasive tools we have to help you get back to the activities you love pain-free.
