SUPER V VULCANIZED SOLE:The new Super V vulcanized sole pattern has been designed with grip, smooth flex and long wearing durability in mind. The Super V is built around Globe's new vulcanized comfort/support last shape. It tucks in through the arch area for support but has an optimal forefoot width for a great universal fit. Globe's S-Trac lug pattern and additional material thickness in the toe and heel ensure long wear and excellent grip.
