The seller, who wears a size 14 shoe, claimed the socks had been worn for 19 straight days during gym sessions, work shifts, and daily use before being listed on the market.
According to FootHubb users, the socks were described as “drenched,” “rank,” and “absolutely overpowering,” quickly pushing the listing into viral territory.
Following the attention, SockMarketX data showed the listing surge roughly 6% in market value as collectors rushed to watch the rare N-grade posting.
Inside the FootHubb SockMarketX Grade Scale
FootHubb’s official SockMarketX grading system ranks socks based on wear duration, sweat intensity, and overall condition.
FootHubb SockMarketX — Official Grade Scale
- F · Fresh — Light scent, minimal wear, 1–3 days. Entry level.
- S · Stinky — Noticeable sweat smell, 2–5 days of wear. The everyday standard.
- R · Rank — Strong, persistent smell, 4–9 days. Heavy labor or activity required.
- X · Extreme — Intense, overpowering condition, 7–14 days. Reserved for serious wear.
- N · Nuclear — Maximum grade. Rank and drenched, 12–30 days. The rarest and most valuable tier on the market.
According to analysts, true N-grade listings were normally exceptionally rare but now they’re becoming more common.
Big Feet Continue Dominating the Market
The viral Norfolk listing also highlights a major trend currently dominating SockMarketX: buyers overwhelmingly favor men with larger feet.
Recent FootHubb data found that 63% of sock purchases in 2026 involved men with foot sizes between 13–16, making oversized gym socks and work socks the hottest category on the platform.
One FootHubb trader described the listing as “the perfect storm.”
“Size 14, nearly three weeks of wear, drenched condition, and an actual Nuclear grade? That a wild smell for sure.”
As the listing continues trending upward, FootHubb users are now closely watching whether the N-grade socks climb even higher in value than its $160 listing over the coming days.
