The New Balance 608 is often chosen for comfort first, so the fitting conversation starts with space. If the shoe is too narrow, the cushioning will not matter much by the end of the day.
Here at Smiths, we can help check whether a 2E or 4E width gives your foot the right amount of room. The heel still needs to feel secure, but the forefoot should not feel squeezed or pushed against the sides of the shoe.
The 608 also has a more structured feel than many lightweight trainers. That can be useful if you want a firmer everyday shoe, especially for walking, work or general daily wear.
Bring in the shoes you currently wear if you have them. Pressure marks, worn-out midsoles and tight spots usually make it clear whether the 608 is the right type of fit to try next.
