Product:
Here we have a Men Oxford Shoes like this one. In this case are many SKUs for different models, colors, and sizes.
The product price was in the range $34,99 up to $89,99 depends on the model
Total sales:
We have $14 988,50 sales, 298 orders, and 307 units sold here.
The least sales were in the 1st month. The most of sales were in the 3d month, when sales were pushed by Amazon PPC. After 3d month, Amazon's PPC budget had been gradually decreasing, affecting sales.
So, the least sales are $697.41 per month and the most are $4,425.77 per month.
Refunds:
Here we have 27 refunds. Total refund costs is $1 378,92 and refund rate is 8,79%.
If we look at P&L details, we'll find that the higher refund rate was 21.05%. It's relating to 8 refunds of 38 units sold. It's not a usual situation, but rather an anomaly. At the same time, the lowest refund rate was 5.36%. It's relating to 6 refunds for 112 units sold, that looks pretty good for a such count of sold units.
Cost of Goods:
On 1688 you may find the same product for $6-40.
Here, we have a cost of goods in range of $6-$10 per item in this case. It was depend from the shoes model, and month of delivery.
So, here we have total COGs of $2 517,41.
Advertising:
Here we have 63 units sold via advertising and 244 units sold organically. Total ad spend is $3 877,95, and real ACOS is 25,87%. You may read about what ACOS is here.
So, if we look at P&L details, we'll find that the first month was without advertising.
- In the second month here was launched Amazon PPC to push sales. The start budget was $560.44 and the final real ACOS for the first month was 19.56%. That's actually a good one ACOS. The final margin was 29.59%.
- Next month, the budget was increased more than 3 times, up to $1, 673.05. At the same time real ACOS was raised to 37.8%, and with other expenses margin had fallen to -16.61%.
- For 3d month, the advertising budget decreased, and real ACOS kept falling up to 39.53%.
- For the 4th month, the last month of advertising, the budget was $723.07 and real ACOS 29.40%.
So, it was clear that there's no way to scale sales to big figures. As soon as the Amazon PPC budget was increased, the ACOS was raised and the margin was falling.
Profit:
Unfortunately, this case is about the tiny profitable experience. It has generated a $1 133,82 net profit total for 7 months. Its margin is 7,56% only, and its ROI is 45.04% only.
So, if we look at P&L details, we'll find a few months generated losses and unprofitable margin and ROI. These are months with launched Amazon PPC campaigns.
At the same time, in months, when Amazon PPC was turned off, there was a high-profitable margin and ROI, but with a tiny of sales.
Conclusion:
In this case, sales were stopped when it became clear there was no way for scalability.
- Here is a niche with opportunities to generate a good margin and ROI.
- At the same time, it's a too competitive niche, and here's difficult to scale sales.
If you want to find the niche with the opportunity to generate a lot of sales, here we have another case with $14 901 sales on Amazon for 1 month.
Key Takeaways: What This Men's Shoes Case Reveals
This seven-month journey illustrates a common challenge in competitive footwear categories: strong organic performance undermined by advertising inefficiency. The seller achieved modest profitability ($1,133.82 net) with a 7.56% margin, but the path was anything but smooth. When PPC budgets scaled up in month three, ACOS spiked to 37.8%, erasing margins entirely and producing a -16.61% loss for that period.
The data tells a clear story about market saturation. Organic sales accounted for 244 of 307 total unitsânearly 80% of volumeâwhile paid advertising drove only 63 units at a 25.87% blended ACOS. This inversion suggests the listing had natural demand but faced stiff competition for paid placements. In months without PPC spend, margins remained healthy, proving the product itself was viable. The problem wasn't the shoes; it was the cost of customer acquisition in an overcrowded niche.
Refund rates also warrant attention. The overall 8.79% return rate is manageable, but one anomalous month saw 21.05% of units returnedâlikely due to sizing issues or a bad batch. Footwear is particularly vulnerable to fit complaints, making accurate size charts and high-quality product photography non-negotiable. Sellers in this category should budget 10-12% for returns as a baseline and monitor feedback closely for recurring complaints about fit or quality.
Ultimately, this case underscores a strategic principle: not every product can scale profitably with paid ads. The seller wisely stopped campaigns when diminishing returns became apparent. For private label sellers evaluating shoe niches, the lesson is clearâprioritize categories with lower PPC costs or differentiation opportunities that justify higher ad spend. Otherwise, even a technically profitable launch can trap capital in a low-margin treadmill.
