Vibram Five Fingers Classic, Your Best Choice

Classic Five Fingers feature a “Non-marking Vibram TC1 performance rubber soles protect your feet and provide a sure grip over a variety of terrain. A thin, abrasion-resistant stretch polyamide fabric fits low on the foot—for comfort and quick drying.”
The Classic upper only rises to the beginning of the instep making the Classic open-aired and the most minimalist, outdoor-use model in the Vibram line-up.
The “razor-siped” rubber sole on the Classic is the standard, original Vibram Five Fingers sole ,same as with the KSO, Flow, and Sprint models. Razor siping is just little jagged cuts that expand when the Vibram rubber sole is bent or flexed. This can increase surface grip on many surfaces. That said, the standard VFF sole can be slippery in muddy conditions due to the lack of cleating.
Vibram Five Fingers Classic shine most when worn “loose” for everyday, casual wear, but many buy them as their first pair of Vibrams and then move on to top-strapped models (like the KSO, Sprint, Flow, or KSO Trek).
Like the Sprint, the Classic has no EVA in the midsole meaning the only thing between your foot and the ground is the 3.5 mm rubber sole and a thin bit of yellow sole fabric.An elastic bungee cord that runs the rim of the shoe and cinches behind the heel. If you don’t plan on using the bungee cord, it can be permanently removed.
