There’s nothing quite like the buzz of slipping on a brand new pair of runners. They feel springy, cushioned, full of promise — like you’re ready to dash around the Tan Track or tackle a Sunday netball game.
But before you turf out your old faithfuls and clock up the kilometres in your flashy new pair, here’s something I’ve learnt both from clinical experience and my own missteps: new runners can make you or break you if you don’t wear them in properly.
When I was training for my first Melbourne Marathon (pre-kids, when I thought “free time” grew on trees), I learnt this the hard way. I swapped my shoes overnight, took off for a long run, and wound up hobbling into the clinic the next day with hip pain. Lesson learned. Let’s make sure you don’t have to learn it the hard way too.
When Should You Replace Your Runners?
Most running shoes will serve you well for about 6 months or up to 800 kilometres, whichever comes first. I know it’s easy to fall into the trap of thinking, “But they still feel fine!” when your runners are moulded perfectly to your foot, practically like a second sock.
But here’s the catch: while your shoes might still feel comfy, the midsole cushioning — the bit that protects your joints from hard surfaces — is quietly wearing down with every step. What we can’t see is often what causes the most trouble.
Over time, that squishy sole flattens out like a pancake, changing how your foot interacts with the ground. Instead of helping you absorb shock, tired runners put all that impact straight into your ankles, knees, hips, and even your lower back. In fact, I’ve treated more rolled ankles and calf strains in seasoned runners than first-timers, purely because they didn’t notice their shoes had clocked up too many miles.
Signs You Might Need New Runners:
- Less spongy feeling underfoot
- Visible wear on the outer sole (especially at the heel or ball)
- Achy joints after walking or running (hips, knees, ankles)
- Developing blisters or hot spots where you never used to
In clinic, I usually recommend doing a runner check-in around the 6-month mark if you’re wearing them regularly — whether that’s for your morning Bayside walk, gym sessions, or pounding the pavement at Parkrun.
Don’t Throw Out Your Old Pair — Yet!
Here’s a tip I share with patients at Well Heeled Podiatry all the time: When you buy a new pair, hang onto your old runners for a little while longer.
It can take around 2–3 weeks for your body — and your gait — to adjust to the fresh support of new shoes.
New runners are firmer, tighter, and more structured compared to your old, broken-in pair. Your muscles, joints, and tendons need time to “recalibrate” to this new feeling.
Switch too quickly, and you could end up dealing with sore knees, hip twinges, or even lower back niggles.

Melbourne’s footpaths are pretty unforgiving — lots of concrete and uneven surfaces. Living locally in Bayside, I see how harsh it can be on shoes (and bodies!) compared to say, softer suburban trails or bush paths. You might need to replace runners a little sooner if you mainly exercise on footpaths or roads.
How to Wear in Your New Runners (Without Wrecking Your Joints)
If I had a dollar for every time someone told me they “broke in” new runners by doing a 10km run straight out of the box… well, I’d have a tidy little side hustle! Properly fitting new runners is one of the best ways to avoid injury and keep your body happy. It’s not about being overly cautious—it’s about giving your muscles and joints a chance to adapt gradually.
This is the same advice I give to my Auskick parents, weekend netball warriors, and patients gearing up for events like Run for the Kids or the Melbourne Marathon. It doesn’t matter if you’re walking the dog around Albert Park or sprinting up Anderson Street hill — gradual is best.

Activity Plan |
Extra Tips |
|
1 |
Wear casually for 1–2 hours at a time. Walk short errands. |
Swap back to your old runners after an hour or two. Wear thicker socks to prevent blisters. |
|
2 |
Build up casual wear to 4–8 hours. Start with light exercise. |
Run or walk at 25% of your usual distance. Listen to your body. |
|
3 |
Increase exercise gradually. |
Run or walk at 50–75% of your usual volume. Mix in old runners if needed. |
|
4 |
Full transition to new runners. |
Return to full running/walking volume if no aches or pains are present. Celebrate with a post-run coffee! |
Your Step-by-Step Checklist for Happy Feet
Day 1 to Day 3
- Foot Roll: Gently roll a massage ball under your arch for a minute before and after wearing new shoes. (Tip: Keep a ball by the front door. It’s too easy to forget otherwise!)
- Short Stints: Wear your new runners for short periods — shopping runs, a walk to grab a coffee, or school pickup.
- Swap and Save: After 1–2 hours, switch back to your comfy old pair.
Day 4 to Day 10
- Stretch It Out: Stretch your calves, hamstrings, and hip flexors daily. (Trust me, your hips will thank you later.)
- Increase Casual Wear: Aim for 4–8 hours in new shoes casually before you think about exercising in them.
Week 2 Onwards
- Ease Into Exercise: Start with just 25% of your usual run or walk. For example, if you normally walk 4km daily, start with just 1km in your new shoes.
- Alternate Pairs: Especially important if you’re doing higher-impact sports like footy, running or tennis.
- Keep Tabs: If you notice anything like:
- Knee pain
- Hip stiffness
- Heel pain
- Blistering
Pull back immediately and extend the wear-in period another week.
Socks Matter More Than You Think
Here’s something people often overlook: New runners are tighter across the toes and heel.
Wearing slightly thicker, cushioned socks — especially in that first fortnight — can prevent blisters, rubbing, and irritation.
In our Melbourne weather (hello, four seasons in a day), I recommend moisture-wicking socks too — nobody wants soggy feet halfway through a run at The Tan!
Pro tip: If you find the toe box feels cramped even with normal socks, it’s worth having your sizing checked. (We often assess this at Well Heeled Podiatry with pressure mapping.)
When to Get Help
If you feel like:
- Your new runners still feel “wrong” after 2–3 weeks
- You develop consistent aches or blisters
- You’re unsure which runners match your foot type (especially if you wear orthotics)
It’s time to book a Podiatry Assessment. We can check your gait, look at your foot mechanics, and — if needed — write you a Referral Script for expert-fitting stores.
Wearing in new runners isn’t complicated — but doing it right can mean the difference between running your personal best or limping into the clinic.
A few smart steps now will help you walk, jog, or sprint into your next goal pain-free and stronger than ever.
And if your feet or joints aren’t happy, even after following all the right steps, we’re always here to help at Well Heeled Podiatry.
Because every step you take should feel like a step forward, not a setback.
