About the Nike Flex Train 'Black'

The Nike Flex Train 'Black' outfits the versatile training shoe in an essential two-tone design. The black mesh upper features contrasting white Swoosh branding and an elastic band that wraps around the heel for lightweight support. The sneaker rests on a full-length foam midsole. The outsole is designed to reduce weight, highlighted by durable rubber that lines the perimeter. Flex grooves allow for a smooth transition and comfortable stride.

Seller was quick to ship the item, it was packed very well, which is good, because FedEx did not treat the box kindly, lol. The shoe’s survived in great shape and are exactly as described. Thanks! A++++ seller.
