The Splaff belt looks more like a belt than a tire whereas the ZPG is basically an inner tube with Velcro. I am, in fact, wearing the ZPG belt while I write this review after a bike ride, but the Splaff belt is classier and more functional.
I think that these flat shoes would be much more comfortable with arch insoles and will definitely give them another chance. … We have coupon codes for discounts if you are interested, so drop us an email or leave feedback.
