Right Sized Rain Boot:

• At the foot level: The first thing to keep in mind is that there is sufficient space at the tip level so that the toes comfortably move. The heel portion of the shoes should easily lift without hurting. But the boot should not slam while walking else the boot is too large. Further, it is important to check whether there is ample space to wear the socks inside the boots. It is important especially important during the cold and rainy season when an additional layer of insulation is required. 
• Calf level: A classic rain boot is tall enough and sits high on the leg. Hence it is vital to know about the width of the calf. The rubber being a rigid material could hurt you hence ensures the opening of the calf is wide enough so that your leg could slip in easily even with pants. 
• Flexibility: As rubber is not the most flexible material; hence, it is advised to opt for a rain boot with the relatively softer sole. It will help in long walks and quicker strides without hurting you.
• Insulation: Rain boots are ideal to be worn all year long irrespective of rain showers. In summer a 100% rubber crafted rain boot will work if you love jumping across puddles. While on the other end on soggy autumn days and sudden spring showers, an insulated boot is ideal. Boots that come with lining not only ensure a better thermal capacity but are also comfy to wear.

• Style: It is ideal to focus on style while choosing your rain boot only when you wear shoes occasionally or on a special day. However, it cannot be ruled out that style, along with comfort, makes a perfect combo.
• Weather: Another important factor to be considered is the weather or the climatic conditions you live before buying the rain boots. While if you are staying in the cool temperate region, it is ideal to prefer a boot where you can wear an additional pair of socks to keep you warm.
• Traction: It is ideal for maintaining traction while walking in wet surfaces. Hence you should check the bottom of the outsole while buying the boots. A shallower set of lugs are ideal for walking in concrete, smooth, pavements, tiles and in short, is ideal for Urban areas.  The outsoles with deep lugs are ideal for walking in rough terrain and uneven and unstable surfaces like trails, mud, grass, and rock.

Clean the soles of the boots using a scrub brush and water. Dry up the boots using a clean rag. Be cautious, and air dry your shoes rather than placing them under sunlight or exposing the shoes to the dryer. The reason being heat can dry and age the rubber and result in shrinking or deformation of rubber.
• Interior:  Rain boots are impermeable, and if you do not wear socks, it could result in moisture inside the boots due to sweating. Else you will be sloshing around all day and may return with foot fungus. To absorb the moisture from the interior of the shoes, stuff the interior of your rain boots with a bunch of newspaper.  Once the newspapers fully absorb the moisture then gently remove the stuff of the newspaper from inside of your shoes. To remove the foul odor from your rain boots, you can slightly spray mist vinegar and water into the boot. Then wipe the interior off with a cloth, especially clean the heel and the region. Let the boot air dry in a cool place for about 24 to 48 hours.
