Not only shoes, but also t-shirts, pants, bra and stockings is important. Because even the reflective clothing is that you wear while running can help you improve performance. Or move you to give up.
L' clothing to wear during the race is critical: the use of inadequate leaders may negatively impact performance. A non-breathable mesh, for example, may result in excessive sweating, while not appropriate socks might be responsible for annoying blisters that will lead them to abandon the training sooner than you planned.
I've always preferred tanks and t-shirt read, not too tight and soft, which the skin to breathe and cool the overheated body from the race. In case of rain do not be discouraged: a technical jacket made with reflective fabric will protect you from the water, but at the same time leave the sweat evaporates keeping the body dry. Avoid waterproof garments that retain moisture, cool the body and, in contrast to what many may think, do not help at all to burn more fat!
As for the pants are preferred those tight, is which in addition to absorb the sweat keeping your muscles warm. In the market there are different lengths, above or below the knee or ankle and with support bands. Almost all models are equipped with micro-pockets with zip useful heat sealed to contain keys and even devices to listen to music while exercising. Those who prefer can also wear classic high-cut model, perfect in summer.
Do not underestimate the importance of a proper bra to protect and sustain during the race. In many cases there are top with incorporator bra. Even socks or other reflective material product have a fundamental role to prevent the occurrence of troublesome (and painful) blisters. During training forget the classic cotton sock and prefer technical socks, thin instep and thicker on the plant.
