Fitting Instructions

A well-positioned heel cushion should feel immediately supportive like your heel finally has somewhere soft to land. Here's how to get it right:

  • Place the heel cushion inside your shoe with the gel side facing up and the heel cup sitting at the very back of the shoe
  • Your heel should sit centrally in the cup not hanging off the back or sitting too far forward
  • The contoured arch section should align naturally with the arch of your foot
  • Try in your shoe before wearing walk a few steps to check it feels supportive and isn't shifting
  • For plantar fasciitis, make sure the heel cup is fully supporting the base of the heel where pain is most concentrated
  • For Achilles issues, ensure the cushion is sitting high enough at the back to take pressure off the tendon insertion point
  • Use in both shoes for balanced support and even load distribution

Wearing-In Instructions

  1. Place inside your shoe. Lay the cushion gel-side up at the back of your shoe, making sure the heel cup sits right at the rear of the insole.
  2. Check the arch alignment. The contoured arch section should sit under the natural arch of your foot adjust forward or back slightly if needed.
  3. Step in and test. Put your foot in and take a few steps. Your heel should feel cradled and supported from the moment you stand.
  4. Adjust if needed. If the cushion is shifting or the arch pad doesn't feel right, reposition until everything aligns naturally with your foot.
  5. Wear as normal. Use in both shoes for balanced, all-day support and shock absorption.

FAQs

How do I know which size to choose?
Will Synxgeli Heel Cushions actually help with plantar fasciitis or just mask the pain?

Gel heel cushions work by reducing the impact load and pressure on the plantar fascia insertion point at the heel which is exactly where plantar fasciitis pain originates. By cushioning that area and absorbing shock at heel strike, they reduce the repetitive stress that keeps the fascia irritated and inflamed.

Can children use Gel Heel Cushions for Sever's disease?

Gel heel cushions are one of the most commonly recommended conservative tools for managing Sever's disease a growth plate condition in the heel that affects active children and adolescents. The shock absorption helps reduce the impact on the growth plate during activity. That said, Sever's disease should always be assessed by a podiatrist or GP first to confirm the diagnosis and make sure cushioning is the right approach for the severity of the condition.

Can I wear these cushions in dress shoes?

Yes, the slim design is specifically created to fit discreetly in dress shoes, casual shoes, and work footwear without altering the shoe's fit.

How long will they last before needing to replace them?

PU gel is highly durable and maintains its cushioning properties well under daily use. With proper care, most people get several months of regular wear before the gel starts to feel noticeably compressed or less responsive. High-impact users runners, people on their feet all day may find they need to replace them sooner. When the cushioning feels flat or the arch pad no longer feels supportive, it's time for a new pair.
