If You Underpronate…
Your…
feet and ankles don’t roll inwards enough when you run – a rare condition. This movement would normally help to absorb shock every time your feet strike the ground.
You need shoes that… encourage the inward movement of the foot (pronation). Look for a soft midsole, and a curved last (the shape around which the shoe is built). Avoid shoes with added stability features, such as medial posts (these are firm sections on the arch side of the midsole, designed to limit pronation).
Asics Gel Cumulus £65 
(pictured)
Weight
356g
A straightforward, smooth-riding, everyday running shoe, with rear- and forefoot cushioning inserts, two widths, and a notably soft midsole. Testers appreciate its snug rearfoot fit, roomy forefoot and light, easy feel, even if the softness doesn’t make it a shoe for out-and-out speed.

New Balance 880 £60
Weight
347g
The 880 has similar qualities to the Asics Gel Cumulus, though it offers the bonus of width options. The upper has a roomy toe-box and the carbon rubber outsole gives the 880 a heavier-duty feel than the Cumulus.

Mizuno Wave Precision £59.99
Weight
295
A model at the lighter, faster end of the daily running shoe market, or the top end of the ‘performance training’ category. To aid cushioning and smoothness, Mizuno’s rippled Wave plate is made from rubber rather than its normal plastic, and the whole shoe has a brisk, responsive feel, with a particularly flexible forefoot. It’s not as soft as the Gel Cumulus, but it’s slightly more curved, which will make it just as suited to underpronators.
