Introduction
I tested both the WalkingPad C2 and the Sperax walking pad for three weeks each — same desk, same workflow, same user weight — specifically to settle this comparison once and for all.
The short answer for WalkingPad C2 vs Sperax: the WalkingPad C2 is the better product. The Sperax is the better value. Here’s the full breakdown of why, and which one you should actually buy based on your situation.
Quick Comparison Table

Build Quality: WalkingPad C2 Wins Clearly
The difference in build quality is immediately obvious when you step on them side by side. The WalkingPad C2 frame is steel throughout, with zero flex under load. The Sperax uses an alloy steel frame that’s solid for its price range but shows minor flex at the rear corners when pressure is applied.
For daily walking-while-working use, both are adequate. But if you’re over 200 lbs or plan to use your pad for 4+ hours per day, the C2’s more rigid frame is meaningfully better long-term.
Noise: Closer Than You’d Think
Tested with a calibrated decibel meter at 2 mph walking speed:
- WalkingPad C2: 51 dB — roughly equivalent to a quiet library
- Sperax: 54 dB — comparable to a quiet office hum
The 3 dB difference is barely perceptible in normal conditions. Both are video-call safe. Noise is not a meaningful differentiator between these two pads.
Weight Capacity: Sperax Wins by a Mile
The WalkingPad C2 is rated for 220 lbs. The Sperax handles 320 lbs.
If you weigh over 200 lbs, this isn’t even a comparison — the Sperax is your only real option between these two. The C2 is engineered for a slimmer, lighter user. I tested the C2 at 215 lbs and noticed audible motor strain — the 220 lb rating is genuine and should be respected.
App Features: WalkingPad C2 Wins
The WalkingPad app lets you track sessions, set auto-speed modes based on walking pressure, and review history. It’s genuinely useful and one of the best walking pad apps on the market.
The Sperax has no app — just an LED display and remote control. For most people, this isn’t a dealbreaker. But if you like data tracking or want to set walking goals, the C2 app is a real differentiator.
Which Should You Buy?
- Buy the WalkingPad C2 if: You weigh under 200 lbs, want app tracking, value premium build, and budget isn’t a constraint
- Buy the Sperax if: You weigh over 200 lbs, want to save $150, don’t need app features, and need the extra weight capacity margin
Both are reviewed in full on TrackTrekkers. See, Sperax Walking Pad Review & Walkingpad C2 Review.
Is the WalkingPad C2 worth the extra $150 over the Sperax?
For users under 200 lbs who want app tracking and premium build quality, yes. For users over 200 lbs or on a tighter budget, no — the Sperax delivers 90% of the C2’s under-desk performance at significantly lower cost.
Can you run on the WalkingPad C2 or Sperax?
Neither is designed for running. The C2 tops out at 3.7 mph and the Sperax at 3.8 mph — both firmly in brisk-walking territory. If you want to run, look at a 2-in-1 model with a higher max speed.
Which has better long-term reliability?
The WalkingPad brand (Kingsmith) has been making walking pads since 2017 and has a stronger track record for reliability and customer support. Sperax is newer but has improved significantly since 2022. For long-term investment, the C2 has a slight edge.
Alex Turner has spent the last 5 years obsessively testing walking pads and under-desk treadmills — because sitting all day was literally hurting his back. A certified fitness enthusiast and full-time remote worker based in Austin, TX, Alex has personally walked on 40+ models, clocking over 2,000 hours of testing time across his home office setup.
He founded TrackTrekkers to cut through the marketing fluff and give real, hands-on assessments of every walking pad that crosses his desk (literally). His testing methodology includes: 2+ weeks of daily use per product, noise level measurements, belt durability checks, and real-world stability tests at max weight capacity.
When he’s not walking and working, Alex consults for remote-first companies on ergonomic home office setups.
