The GEOX U664JA Flextride are men's leather lace-up derby shoes that join a classic cut with a flexible sole designed for comfortable walking. We chose them at Calzados Vesga because they work as well for the office as for the weekend and feel light from the first step. They are available in Black, with smooth leather, and in Chocolate, with a suede-look finish.

A classic derby with a flexible sole
Most dress shoes are chosen for their looks and felt in the foot at the end of the day: a rigid sole, little spring and office hours that take their toll. The Flextride keep the classic derby cut but add a sole with Flextride technology that flexes with the natural movement of the foot.
The microperforated rubber sole is light and glued rather than stitched, which lightens the shoe without losing sturdiness in daily use. You notice it most on long walks or on days with many hours on your feet.
They are a sensible choice if you want a lace-up shoe that works for both work and leisure time, without giving up a polished look.
Design and colours: Black and Chocolate
Black, in a smooth finish leather, is the most sober option and goes with dark suits, dress trousers and dark jeans. Chocolate is a dark brown with a suede-look finish: it is more casual and goes with jeans, chinos, corduroy and knitted jumpers.
In both colours the cut is the same: a rounded toe, discreet stitching and a heel counter. The sole, in the same tone as the shoe, keeps a clean look.
Materials and finish
The outer is leather: smooth in the Black and with a suede-look finish, with a velvety appearance, in the Chocolate. Inside there is a textile lining and the insole is also textile. The sole is microperforated rubber, assembled with glued construction. We do not state the type of tanning or the exact name of the Chocolate finish because they are not in the information we have; ask us if you need it.
How to choose men's derby shoes
When choosing derby shoes, look at the material, the closure, the sole and the fit. Leather adapts to the foot with wear. Laces let you adjust the instep, and a derby, with its tabs stitched over the vamp, is slightly more comfortable than an oxford for high insteps. A flexible sole reduces fatigue over long days.
The Flextride bring these points together in a classic, comfortable design.
Everyday comfort
Flextride technology divides the sole into a geometry that flexes with the natural movement of the foot, instead of bending rigidly like a classic leather sole. You notice it most on long walks or on days with many hours on your feet.
A practical tip: if you have a high instep or wear thick socks, try half a size up. With thin socks, your usual size will be right.
The textile lining and insole give a soft contact with the foot, and the laces let you loosen the fit if your feet swell during the day.
When to wear them They also work well for travel, since the light, flexible sole is comfortable on long days of walking.
For the office, meetings, business lunches, events with a formal or smart-casual dress code, travel and long city walks. Black is the choice for the most formal settings; Chocolate fits better into informal everyday wear. They are not waterproof and the suede-look finish of the Chocolate marks with moisture, so avoid heavy rain.
How to wear them
Black with a dark suit, dress trousers and a fine jumper or shirt. Chocolate with jeans, beige or green chinos, corduroy trousers and knitted jumpers in earthy tones, blues or greys.
Care and maintenance
For the Black, clean the leather with a soft, slightly damp cloth and apply a cream or polish of the right colour from time to time. For the Chocolate, brush it with a suede brush to remove dust and use a protective spray for suede or nubuck before wearing.
If they get wet, let them dry in the open air, away from radiators and direct sun, with newspaper inside. Do not put them in the washing machine.

Our opinion at Calzados Vesga
We think they are a sound purchase for anyone looking for leather lace-up derby shoes that are comfortable for many hours and easy to match. Their strengths are the leather, the flexible sole and the classic cut; their limit is that they are not a Goodyear-stitched shoe, they are not waterproof and the Chocolate needs more care than the Black.
