The wheelchair had a squeaky front wheel.

That's what I remember most. Squeak. Squeak. Squeak. All the way down Terminal B.

Mike was pushing. Dave was carrying my clubs. Tommy was filming it on his phone and laughing so hard he had to stop twice.

I'm 52 years old. I'd just finished the golf trip I'd been planning since my oldest was in diapers.

And I couldn't walk to my own gate.

Twenty years we talked about that trip. Four buddies, four days, a stretch of old links courses on the coast where you walk every hole. No carts. That was the whole point.

My wife packed me a sweater and said, "Go. Get away from me for a bit."

I'd never been so excited about anything that didn't involve my kids.

Day 1, I walked 36 holes and felt like a kid.

Day 2, another 36. By the 10th hole, my dogs were barking. By the 18th, the soles of my feet felt bruised. Like someone had taken a hammer to them.

Day 3, I woke up stiff and sore as a board. I took two Advil and two Tylenol before breakfast. Tommy called it my Geritol.

I barely finished the round. I wasn't sure I could make it from the last green to the van.

"Toughen up, Nancy," Dave said.

So I tried.

20 years of planning. 4 days of golf. I missed the one round I flew across the ocean to play.

Day 4 was the course. The one on the calendar in my office for two decades.

I watched them tee off from the clubhouse window with my shoes off and my feet in a bucket of ice.

Then the wheelchair. Then the squeak.

It took me another 3 months to find out why it happened.

It wasn't my age. It wasn't my shape. And it wasn't my shoes, which cost me $220.

It was something inside them that I'd never once looked at.

Nobody said anything on the flight home.

That was worse than the jokes.

Mike had planned that trip for a year. Dave had taken time off he didn't really have. And on the last day, they spent the round they'd waited 20 years for checking their phones to see if I was okay.

I felt like I'd ruined it for everybody.

Back home, I did what most guys my age do.

I typed my problem into the golf forums.

Half of them said I was out of shape. "If you hurt, you're not in shape." "Get in shape. 95% of the time that means lose weight."

The other half said it was just my age. "Welcome to middle age." "You can't beat father time."

So I decided they were right. I was just getting old.

I kept a bottle of ibuprofen in the side pocket of my golf bag.

I stopped playing back to back days.

After every Saturday round, I'd come home and be stuck on the couch for the rest of the day. The first 10 minutes of Sunday morning were the worst. I'd walk to the coffee maker like I was barefoot on a gravel driveway.

Then I did the thing I swore I'd never do.

I rented a cart. $40.

I rode all 18 holes that day and played fine. My feet felt fine.

And I hated every minute of it.

Because walking was the whole reason I play. The quiet. The walk between shots to cool off after a bad one. The fairways I'd walked with my dad.

That night I got a text from Mike.

"Same trip next year? Already got a hold on the tee times."

I stared at that text for a long time.

Because I knew if I couldn't walk 18 now, I'd never walk 90 again. And if I started riding, I'd never stop.

That's how it goes for guys like us. The cart is the beginning of the end.

I didn't text him back for three days.

On the third day, I texted Mike back.

"Count me in."

Then I went to war with my feet.

First, the shoes. I already owned the $220 pair. So I bought another one. Then a spikeless pair. Then a waterproof pair that was on sale.

I'd walk around the store in them and they felt like clouds. Then I'd walk a round and realize they weren't for me either.

By June I had so many golf shoes my wife made me clear out half the garage shelf.

Next, the insoles. I grabbed a pair off the wall at the sporting goods store.

They didn't do squat.

So I went to a podiatrist and got custom orthotics. They cast my feet in foam and everything. "Not the $20 ones," a guy on the forum told me. Mine were a couple hundred bucks.

They were hard as a dinner plate. Great for standing. Brutal by the 12th hole.

Then the little stuff. Silicone heel cups. Twenty-dollar merino wool socks. Knee-high compression socks that took me five minutes to get on and made me look like I was going to a 1985 tennis match.

At night, I rolled my feet on a frozen water bottle. Then a golf ball. Then a tennis ball. My wife bought me a massage gun for Father's Day.

Over a thousand dollars.

And by the back nine, my feet still felt bruised.

That's when I got angry.

Not at my feet. At the whole golf industry.

Think about it. They'll sell you a $600 driver that adds 8 yards. They'll fit you for irons down to the degree. They'll sell you a $5 ball because it spins 200 more RPMs.

But the one thing that touches the ground on every step of a 5 mile walk? Nobody ever talks about it.

I found out why one night in the garage.

I was boxing up my $220 shoes to sell them online. I pulled the insole out to check the size.

And I just stood there holding it.

It was as thin as a mouse pad. I held it up to the garage light and I could almost see through it.

I sat down on the garage step with that insole in my hand.

And for the first time, I actually thought about it.

Golf shoes are built for the swing. The soles are stiff so you stay planted when you turn. The spikes grip. That's where all the engineering goes.

The insole? It's a thin cover sheet sitting on top of a stiff sole.

That's why every pair felt like clouds in the store. Fifty steps on carpet, and anything feels good.

But a walking round is 18,000 steps on hard ground, hills and cart paths.

One step on a thin liner doesn't hurt.

18,000 of them do.

That's why I felt fine on the front nine.

That's why my dogs were barking by the 10th.

And that's why the soles of my feet felt bruised by the 18th, every single day of that trip.

It also explained the cart day. I rode, took a third of the steps, and my feet felt fine. It was never my age. It was the count.

Then I thought about the drugstore insoles. They were soft. That was the whole selling point.

But soft foam squishes under your weight. One soft layer, asked to cushion your heel, hold up your arch and keep your foot steady through the swing, all at once.

It can't do all three. So it ends up doing none of them well.

The custom orthotics had the opposite problem. All support, no give. Like walking on a dinner plate.

And the $220 shoes? Beautiful sole. Same thin liner as everything else.

So I didn't need softer.

I needed something that did three jobs with three separate layers.

Something to hold my arch up through the swing. Something to take the hit, step after step. And something to cup my heel so it stayed put instead of sliding around.

For 18,000 steps. Then 36,000. Then 90 holes in 3 days.

I didn't think that existed outside a podiatrist's office.

Then Tommy, the guy who filmed me in the wheelchair, sent me a link.

"Saw this and thought of your squeaky wheel."

I almost didn't open it. Tommy sends me a lot of stuff, and most of it is videos of guys falling into ponds.

But "squeaky wheel" got me.

The link was to a pair of insoles called Naprelle Cloud Insoles.

And the first thing I saw was that they aren't one layer.

They're three layers, and each one has its own job.

On top, there's a side arch support that holds your arch up instead of letting it collapse when you load into your swing.

In the middle, there's an enclosed honeycomb gel layer that takes the hit every time your heel comes down.

And on the bottom, there's a memory foam base with a deep U-shaped heel cup that cradles your heel, so it stays centered instead of sliding around.

I read it twice. Then I went and got the thin liner off the garage step and set it next to my laptop.

Something to hold my arch up. Something to take the hit. Something to cup my heel.

That was exactly what I'd figured out sitting in the garage the night before.

That's what sold me.

Every fix I'd bought had done one of those jobs, at most. The shoes looked great and had nothing underneath. The orthotics were all support and no give. The drugstore insoles tried to do everything with one soft layer.

This was the first thing I'd seen that gave each job its own layer.

Then I saw this line:

In Naprelle's in-house test, the full insole absorbed 56% more shock than a regular flat stock insole.

A regular flat stock insole. The same mouse pad that came in my $220 shoes.

And there was one more thing I didn't expect.

You trim them to fit at home. No casting, no appointment, no couple hundred bucks.

They cost less than one round of golf. So I ordered a pair.

That Saturday, I put them in my $220 shoes and walked 18 at my home course.

I didn't rent a cart. I didn't take anything before the round.

I kept waiting for the 10th hole.

Nothing.

On 18, I realized I hadn't thought about my feet once the whole round.

I came home and mowed the lawn instead of lying on the couch.

Sunday morning, I walked to the coffee maker like a normal person.

Then I did something I hadn't done in over a year.

I walked 18 again. Back to back.

When I got home, I texted Mike.

"Book it. I'm walking every hole."

Here's the funny part.

The next weekend, I went to grab a different pair of golf shoes off the garage shelf. My waterproof pair, because it was supposed to rain.

I had to pull the insoles out of my $220 shoes and swap them over.

Then I forgot to swap them back. Walked the next round on the mouse pad again. By the 10th, I knew it.

That's when it clicked. I have five pairs of golf shoes. Every one of them came with the same thin liner.

So I went back and got the bundle. Five pairs. One for every pair of golf shoes on that shelf.

My advice: If you walk your rounds, don't wait for your feet to ruin a trip. Put a pair in every golf shoe you own, and one in your walking sneakers too. The bundle is the only way I'd do it.

Here's how it stacks up against everything else I tried.

Naprelle Cloud Insoles

Side arch support, enclosed honeycomb gel and a memory foam base with a U-shaped heel cup.

Men's 5 to 15. Women's 6 to 16. Trim to fit.

Try them for 90 days. If they're not for you, you're covered by Naprelle's 90-day guarantee.

The trip is booked for next September. Same four guys. Same coast.

Day 4 is the same course I watched through the clubhouse window.

Tommy already told me he's bringing the wheelchair video to dinner.

That's fine.

I'm going to watch it on the flight home. From my seat.

If you walk your rounds, don't find out the way I did.
