The short answer: Insert the insole with the arch support on the inside (medial side) of your shoe, remove the original insole first, and if your shoe is too tight, trim the insole from the toe end using the size guide. Do not use them in shoes without removable insoles.
Before you even take the Powerstep Pinnacle Maxx out of the box, look inside your shoe. If there is an existing insole, pull it out. You need that space for the Powerstep. If the original insole is glued in and cannot be removed, these insoles are not suitable for that shoe. They are thicker than most, so they will cause pressure points and a tight fit otherwise.
Most athletic shoes, hiking boots, and work boots have removable insoles. Dress shoes and some casual shoes might not. If you are unsure, check the manufacturer’s website or try the insole on top of the original first to see the thickness difference.
The Powerstep Pinnacle Maxx come in full sizes, and they often run true to size. However, if you are between sizes, size up because you can always trim down. The insoles have a printed line at the toe area that indicates where to cut for a half size smaller. Use sharp scissors and cut along the line carefully, ensuring you do not trim the arch area.
To see if you need trimming, place the insole on top of the original insole that came with your shoe. If the Powerstep is longer than the original, you will need to trim it. Cut only a little at a time, as you can always cut more, but you cannot add material back.
The Powerstep Pinnacle Maxx has a distinct medial arch support (on the inside of your foot). When you look at the insole, you will notice the heel cup is deeper on one side. That side should sit against the inner side of your shoe (the side that touches your big toe if you stand normally). If you put it in reversed, the arch will dig into your foot and cause discomfort.
Slide the insole in from the heel first, pushing it all the way back so it sits flat against the bottom of the shoe. Then press down the front part. Make sure the edges are not curled up. If the insole is curling at the toe, it might be too long. Trim a bit more.
Once the insole is inside, put on the shoe without socks first to feel the arch placement. Then wear your usual socks and walk around your home. Pay attention to any heel slippage or pressure on the top of your foot. The insole should feel snug but not tight. If your toes feel cramped, you need to trim more or the shoe is too narrow.
Also, check that the heel of the insole stays in place. If it shifts when you walk, it might be too small or your shoe’s heel counter is too wide. Some people need to use a thin adhesive tape on the bottom of the insole to keep it from sliding, but Powerstep has a top fabric that grips well.
Do not expect the insoles to feel perfect on day one. The Pinnacle Maxx has a firm arch support that your feet may need time to adapt to. Wear them for a few hours each day, gradually increasing time. If you feel sharp pain or numbness, remove them and re-evaluate the fit. Sometimes the arch support is too high for low-arch feet, in which case you might need a different insole. For most people, a week of regular use helps the insole mold slightly to your foot.
If you are using these in shoes that you wear for running or long standing, consider pairing them with shoes that have a removable insole and a wide toe box to avoid crowding.
To get the most life out of your insoles, proper care is essential. The top fabric can absorb sweat and odors, so regular cleaning helps. Hand wash them with mild soap and cool water, then air dry completely away from direct heat. Do not put them in the washing machine or dryer, as heat can warp the arch support and break down the cushioning. For daily freshness, you can sprinkle a little baking soda inside the shoe or use a shoe deodorizer between wears.
Inspect your insoles periodically for signs of wear. The arch area may flatten over time, and the top fabric can develop holes or tears. If you notice these issues, or if the insole no longer feels supportive, it is time to replace them. Most people replace their insoles every 6 to 12 months, but if you wear them daily in high-impact activities, you might need to replace them sooner. Rotating between two pairs can extend the life of each.
Also, keep your shoes clean inside. Dirt and grit can accelerate wear on the insole. If you have removable insoles, take them out after each use to let the shoe air out. This prevents moisture buildup and keeps the insole fresher longer.
Even with clear instructions, people often make mistakes that lead to discomfort or poor performance. One of the most common is trimming too much off the toe right away. Always start by testing the fit without trimming, and only cut a little at a time. Remember, you can always remove more material, but you cannot add it back. Another mistake is inserting the insole upside down. The arch support should face up and be on the medial side. If you feel a hard lump under your arch, it is probably reversed.
Some users try to force these insoles into shoes that are too small or too narrow. This can cause foot pain, blisters, and damage to the shoe. If the shoe feels excessively tight even after removing the original insole, it is likely not compatible. Also, do not ignore pain during the break-in period. Soreness is normal, but sharp pain or numbness is not. Listen to your body and adjust accordingly.
Finally, avoid using these insoles in shoes without removable insoles. The added thickness can press your foot against the top of the shoe, leading to discomfort and potential injury. If you are unsure, consult a podiatrist or shoe fitting specialist.
While Powerstep Pinnacle Maxx insoles work well for many people, they are not for everyone. If you have a very low arch or flat feet, the firm arch support might feel too aggressive and cause pain. In that case, a softer, lower-profile insole might be better. Similarly, if you have a very high arch, you might need more cushioning than these provide. People with certain foot conditions, such as plantar fasciitis, may benefit from these insoles, but others with conditions like metatarsalgia might need a different design with metatarsal pads.
Also, consider your shoe type. These insoles are designed for athletic shoes, boots, and casual shoes with removable insoles. They are not ideal for dress shoes, heels, or minimalist shoes. If you need an insole for a specific sport, such as cycling or skiing, look for a model designed for that activity. Finally, if you have diabetes or circulatory issues, consult your doctor before using any over-the-counter insole, as improper fit can lead to serious foot problems.
If you try the Powerstep Pinnacle Maxx and find they are not right for you, do not force it. There are many other options available. Our comprehensive shoe insole buying guide can help you compare alternatives and find the best match for your feet and shoes.
No, you should not. The insoles are too thick and will cause discomfort and possibly damage the lining of the shoe. Stick to shoes with removable insoles.
Most insoles like this last 6 to 12 months depending on use. If you notice flattening or loss of support, replace them. Also, if you see visible wear or smell that does not wash away, it is time for a new pair.
It is not recommended. Trimming the sides can affect the structural integrity and support. The only safe trim is along the toe line indicated on the insole. If your shoe is too narrow, choose a different shoe or insole model.
