How sneaker bots work, and where proxies fit

The parts of a sneaker bot (tasks, profiles, accounts, monitors, proxies and servers), what happens during a release, how stores push back, and the legal and terms limits to know.

How sneaker bots work, and where proxies fit

Quick answer

A sneaker bot is software that runs many checkout attempts at once, each one called a task. Every task combines a product, a size, a shipping and payment profile, often an account, and its own proxy IP, so the store sees separate shoppers instead of one machine.

Stores push back with queues, draws, verification and purchase limits. Store terms usually ban automated purchases, so bots are a terms question for sneakers; for event tickets, the US BOTS Act makes bypassing limits illegal.

Diagram: a bot on a server runs three tasks; each task uses its own proxy IP and reaches the store as a separate shopper.

The parts of a sneaker bot

Most retail bots share the same building blocks, whatever the brand. The task is the unit of work; everything else feeds it.

Part What it holds Example
Task One attempt: store, product, size, mode Nike, style code, size 10
Profile Shipping address and payment card Home address, one card
Account A store login, where the store needs one A Nike member account
Proxy The IP the task sends traffic through One static ISP IP
Monitor Watches products and triggers tasks Polls a product page every few seconds
Server The machine the bot runs on A VPS near the store's region

Valor's documentation ties each task group to one site and lets every task pick a proxy group. NSB's task setup has a step to select a billing profile and proxy list. The shape is the same: tasks draw on shared lists of profiles and proxies.

What happens during a release

  1. Before the drop, the bot loads tasks, logs in accounts and tests proxies against the store.
  2. A monitor or the clock starts the tasks when the product goes live.
  3. Each task joins the queue or the draw through its own IP.
  4. Tasks that get through add the size to the cart and submit the profile's address and card.
  5. The bot reports which tasks reached an order confirmation and which failed.

The whole run is one session per task. If a task's IP changes mid-way, many stores treat it as a new visitor. Valor's Pokémon Center guide notes that an IP change sends the task back into the queue, which is why static ISP IPs carry most release tasks.

Where proxies fit

Without proxies, every task leaves from the server's one IP. The store sees dozens of carts from one address and blocks it. Proxies give each task its own address, and the type of proxy decides how that address behaves:

  • Static ISP keeps one carrier IP per task for the whole term, with unlimited traffic. It is the usual pick for Nike, footsites, Pokémon Center and monitors.
  • Rotating residential sends traffic through real home devices and is billed per GB. Bot makers point Shopify stores with proxy protection to residential.
  • Datacenter IPs are cheap and fast, but protected stores flag their ranges.

Our guide to the best proxies for sneaker bots compares the three in detail.

How stores push back

Stores know bots are there. Nike's SNKRS VP said in 2023 that the app sees nearly 12 billion bot entries a month and removes up to 98% of them, as reported by Sneaker News. The common defenses:

Defense What it does Effect on bots
Queues and waiting rooms Let shoppers in a few at a time Tasks need a stable IP to keep their place
Draws Pick winners at random from entries Speed matters less; entry rules matter more
Account verification Phone numbers, member profiles Each entry needs a real person behind it
Purchase limits One pair per person or address Extra orders get cancelled
Bot screening Flags automated patterns and bad IPs Shared or cloud IPs fail first

Nike's draw rules, for example, allow one entry per person per launch product and name scripts that automate entries as grounds for blocking or cancelling.

For sneakers and other retail goods in the US, the main limit is the store's terms, which usually forbid automated purchasing and let the store cancel orders. The Stopping Grinch Bots Act, which would apply the BOTS Act approach to online retail, has been introduced in Congress several times; the 2023 Senate version, S. 3511, was referred to committee. Check its current status before relying on it either way.

Event tickets are different. The US BOTS Act prohibits getting around a ticket issuer's security measures or purchase limits and bans reselling tickets bought that way. The FTC enforces it, and its first cases against three ticket brokers ended in $3.7 million in civil penalties. This is general information, not legal advice.

Get started

If you run a bot, the next steps are choosing IPs and loading them. ProxyLane's sneaker proxies are dedicated static ISP IPs at $3.90 per IP for 30 days, and our setup guide for Valor and NSB shows where the list goes.
